Biodiesel And Its Producing Alternatives

Sunday, April 26th, 2009
Daniel Roshard asked:


In a world where people rely heavily on diesel-powered engines to perform many functions for both agriculture and other known industries, it no longer comes as a surprise if there is a limited supply of derivatives of diesel fuels with traces of petroleum.

Besides the (over)exhaustion of reserves of petroleum fuels, improbability in petroleum sources and supply because of certain economic and political reasons inspired many to look for alternative resources for petroleum-based fuel sources like diesel.

You’ve heard of vegetable oil, animal fat, and recycled cooking oil being used as fuel nowadays. These are what you call Biodiesel.

From the word itself, biodiesel is an alternative to diesel fuel made from renewable or organic sources such as the ones already mentioned above. Biodiesel is produced by means of a reaction between an animal fat or vegetable oil and ethanol or methanol with a certain catalyst. Biodiesel appears as and used as either in its pure form or can be mixed with diesel to be utilized by diesel engines - a petroleum-based biodiesel. Both have yields of glycerin and biodiesel, which are chemically known as asters of methanol and ethanol.

The following presents the major advantages of using biodiesel:

1. It is non-hazardous and biodegradable.

2. It can readily be used in modern types of diesel engines.

3. It is a much more efficient as compared to fuel cells.

4. Thus, it can eliminate the huge allocation of reconstructing major fuel distribution factories and companies.

On the note of producing biodiesel extracts on a macro scale basis, two steps are usually considered:

1. Growing of alternative feed stocks.

Oilseed crops (and animal lipids) are well known sources of biodiesel because of their oil content.

Interestingly, recent programs have been funded to research on the feasibility of using algal species as feedstocks for biodiesel extracts. In fact, there are noted species of algae from which you can extract larger amounts of oil. The same species also grow at very fast rates so production would definitely be efficient. Moreover, most of these species use less water for cultivation, unlike oilseed crops.

Another advantage of using algae as a source of biodiesel is that the species also grow best in salty water, so farms could be built near the ocean without desalinating seawater.

With recent development regarding algae research, that concern is completely obliterated since it was noted that algae could survive in either a hot desert or within areas near waste streams.

Processing the feedstock into biodiesel. This step would be best accomplished by present oil refineries around the world, which are being converted to biodiesel refineries and by new companies building state-of-the-art plants.

Environmentally speaking, the use of biodiesel is basically not alarming. However, further researches regarding on biodiesel producing alternatives should be ventured upon to facilitate a more feasible large-scale biodiesel production.



Uk Boat Owners On The Look-Out For Biodiesel

Sunday, April 19th, 2009
Keith McGregor asked:


As November 1st 2008 approaches and the end to UK Red Diesel derogation, yacht owners are sharing an interest in alternative fuels one being Biodiesel. What are the benefits for boat owners and who will supply it?

Biodiesel refers to a non-petroleum-based diesel fuel made vegetable oils or animal fats.

There are many advantages of marine biodiesel as a marine fuel



Biodiesel serves as a drop-in replacement for petro diesel — no conversion necessary.

Biodiesel when used in boats causes less water pollution – there is less smoke and it is safer to store.

Biodiesel production uses a third less energy than petroleum diesel production.

High lubricity extends engine life

Higher cetane rating (46-62) almost always smoothes engine operation

Biodiesel can be blended with petroleum-based diesel at any ratio

Biodiesel contains essentially no sulfur or aromatics. Blends as low as B20 have reduced soot exhaust by 83%. Biodiesel removes deposits in tanks and fuel systems left by petro diesel.

Cheaper than the current red diesel prices of 88pence per litre even before the additional 54.94p in duty to be added from 1st Nov 2008.



Disadvantages



Doesn’t store as well as petro diesel

Possibility of blocked filters as it cleans the lines out and failed rubber seals as Biodiesel is a better solvent than mineral diesel

Blends of more than 5% (B5) to 95% (B95) may invalidate engine warranties

No Bio Diesel suppliers and blending facilities in marinas or boatyards at present.



Conclusion

Whilst at present there are no direct suppliers of marine biodiesel for boat owners, there are plans for the 2009 Portland Marina in Dorset to supply biodiesel and several marinas advise they have spare tank capacity to store another grade of oil.

A recent farm-based bio-diesel plant in North Wales has been reported as receiving interest from yacht and boat owners already. BML Biofuels, based at Llanfihangel GM, near Corwen is the first plant in Wales - and only the second in Britain - to extract oil by cold pressing oilseed rape (OSR). At the resulting cost 45p-55p/litre for the first 2,500 litres plus tax, it’s then no surprise BML Biofuels has already received maritime inquiries as far afield as Portsmouth since its official June opening.

With the higher cost or red diesel and a government under pressure to meet renewable fuel targets Biodiesel is likely to become a key ingredient in the refueling of motor yachts over the next decade.



Some of the Biodiesel Solvets Used in the Production of Biodiesel

Tuesday, April 14th, 2009
Muna wa Wanjiru asked:


What is a Biodiesel?

Biodiesel can be differentiated from the waste vegetable oils (WVO) or from the straight vegetable oils (SVO) which are used as fuels in some diesel vehicles. Biodiesel is a diesel that is equivalent to the processed fuel which results from the biological sources such as vegetable oils that can be used in unmodified diesel engine vehicles. Biodiesel is considered to be the fuel for future. It is an alternative fuel which is made from renewable resources.

Biodiesel is a very safe fuel which can be used in any diesel engine vehicle. While preparation of Biodiesel does not involve any harmful ingredients and also it does not produce any harmful byproducts. You can prepare Biodiesel at your own place. The ingredients to prepare Biodiesel are triglyceride fat or oil i.e. vegetable which is used in cooking, a strong base like sodium hydroxide (NaOH) or potassium hydroxide (KOH) and a relatively pure alcohol. Biodiesel is one of the cheapest, safest and cleanest fuels available.

Solvents used in a Biodiesel

Large numbers of solvents are used in a bio diesel plant. The types and the solvent used are basically dependent on the type of the plant. The solvents may also be various chemicals used. Alkyl esters are used in many ways. One of such way is it is used as a solvent in the Biodiesel and it also is used as chemical intermediates which is required for the formation of the detergents.

The pure form of Biodiesel can be used in its pure form. This Biodiesel may include unburned hydrocarbons and it also contains carbon monoxides. This is on of the most efficient way to use a Biodiesel especially when the biodegradability and non-toxicity are important factors.

The solvent properties of the bio diesel are at the highest intensity and they may also cause problems with the loosening of lacquer deposits in the tanks which have he lines and fuels. The problem of the solvents with the B100 is more or less a major concern when the use of the blends is made.

Some of the solvents generally used are hexane, isopropanol, methanol, isopropanol, oil etc People also produce Biodiesel from the alkali and acid process. Vegetable oil or the waste cooking oil is used for making Biodiesel. The acid based process which requires waste cooking oil is very economic allover.

Some of the projects which use extensive amount are mentioned below:

In Egypt a project has been undertaken which involves the use of the Jatropha as a potential Biodiesel feedstock. Another project in which the Biodisel Fuel from the non edible Vegetable oil is also under taken as a collaborative project by UNH Biodiesel group and the famous National Research Center (NRC), Cairo. Oil is used in large amount and it is extracted from the seeds. In these projects solvents like oil, methanol, and glycerol are extensively used. The chemical reaction of the solvents and the materials used can be future summarized in the following manner:- Oil + 3 Methanol [using NaOH or KOH catalyst] = 3 Biodiesel (Methyl Ester) + Glycerol. The main objective behind the research was to study the transesterification of the oil extracted to the Biodisel.



The Pro’s and Con’s of Biodiesel

Tuesday, April 14th, 2009
roosterbob asked:


Back then, we failed to realize the implications of our actions or the repercussions of a developed society highly dependent on petroleum and incessantly slave to the dictates of the mighty oil barons.

When automated vehicles were first introduced to the world, could anyone have anticipated the vast impact it will have to the economy? Who would have thought that combustion engines would turn out and be the backbone of today’s society? Decades ago, this idea seemed to be too great to fathom. However, its environmental impact was then, not recognized probably because of lack of foresight.



Biodiesel: Pros


•    Right here and now, what we have is biodiesel. This is an alternative for petroleum-based fuel that boasts a cleaner burn as compared to its expensive and environmentally unsound counterparts.

•    Biodiesel is a  renewable fuel source that stems from various resources including vegetable, canola, palm, and soybean oils.

•    In addition, this fuel releases far less nitrogen oxide, carbon monoxide, and unburned hydrocarbons. And since biodiesel processors convert vegetable oil, it is biodegradable and non-toxic. Do not forget the absence of sulfur products as oppose to petro-diesel. Given this lack of sulfur, biodiesel still possesses the required viscosity to fully lubricate diesel engines, which cannot be easily arrived at when dealing with low-sulfur petroleum products.

•    With the proper biodiesel equipment, the fuel output can be used in almost all diesel engines with modifications that are considered discretionary. Also, having a renewable fuel source will moderate our reliance on foreign oil corporations, or dare we say, the Middle East oil tycoons. If local farmers produce the needed raw material for our biodeisel, then we do not need to import oil because we can manufacture it ourselves, right?



Biodiesel: Cons


•    The fuel generated by biodiesel processors is an inherent solvent; meaning, sooner or later it will trigger the deterioration of various rubber components such as hoses and pumps. Though this can be easily replaced by visiting your local dealer. Sometimes extra tubing is included in a biodiesel expansion pack. This package is ideal if you plan to make batches and batches of biodiesel.

•    Also, this solvent characteristic will clean the injectors and the tank, as well as the fuel lines; the downside is that, blockage is inevitable. But this is not a reason to be worried. Just prepare yourself to a frequent filter change for the first couple tanks of biodiesel.

•    As for the gel point, biodiesel posts higher than that of its petroleum equivalent. This connotes that the former coagulates faster. But, this too, can be resolved by using an anti-gel additive.

•    The last issue lies on the recent introduction of biodiesel. This is fairly new and consumers may have a hard time locating biodiesel processors and kits. Well, a quick search in the World Wide Web is the solution for this one.

Whether you prefer it straight up or mixed (20% biodiesel to 80% petroleum diesel), so long as nature is unscathed, then it is all good. This alternative could be one of man’s greatest achievements. Though this time around, we need to take the time to become aware of its pluses and minuses, including the ideal method of generating, regulating, and utilizing this precious liquid we call biodiesel.



How to Make Biodiesel at Home and With Ease

Thursday, April 9th, 2009
Muna wa Wanjiru asked:


Biodiesel is the best alternative to petrol and petroleum products along with petroleum diesel. Its preparation from biodegradable substances is the primary reason for the diesel being called the Biodiesel. The Biodiesel can be used in its pure form, but is also adaptable to a blend with petroleum diesel.

The preparation of this Biodiesel is a very easy task and can be carried out even in a ranch or farm. Biodiesel can be made through numerous processes. It is easier to make a homebrew Biodiesel than to make it on a large scale or in a refinery. The following are some of the ways that are commonly used for preparing the Biodiesel at home.

1. With the use of Vegetable Oil:

Under proper conditions, waste as well as new vegetable oil can be used for the production of Biodiesel.

a. Preparation of Biodiesel using new vegetable oil:

For the preparation of Biodiesel, there are a lot of kits that are available on the market today. For making convenient Biodiesel, you must first study the kit carefully and must first make small batches of it. For the preparation of a home brew Biodiesel, you will need the following apparatus:

* A blender with Glass jar.

* A scale which weighs upto 0 to 50 gm with the nearest 0.1 gm.

* One quart jar.

* A hand pump;

* A liquid measuring cup;

* Methanol;

* Sodium Hydroxide;

Method:

Take proper care of your guarding equipments and then pour 1 cup methanol in the blender. Put 3.5 gm of sodium hydroxide and put it in the methanol in the blender. Blend the mixture for about 5 minutes. The blended mixture is a very strong base, called sodium methoxide. Please take care to avoid getting in contact with it. Pour one quart of new vegetable oil into the sodium methoxide and blend the mixture for 30 minutes at low speed. Let the mixture to set for around 8 hours at room temperature. The mixture after the setting is a mixture of the Biodiesel, which floats on top of a dark colored glycerol. You can then pump the light Biodiesel out with the help of the hand pump.

b. Preparation of Biodiesel using waste vegetable oil:

The waste oil is more acidic than the new oil because of the high amount of fatty acids that are present in it. You will have to first determine the amount of catalyst needed for the preparation with the help of titration. When you determine how much sodium hydroxide is required, you can follow the same method for the preparation of Biodiesel with the new vegetable cooking oil. The end result is also the same, but there is a white layer in between the diesel and the glycerol. It is the soap and is present if there is even a small amount of water present in the vegetable oil. To remove the oil you will have to warm the oil and when the water settles down, you can remove it by the hand pump or can just pour it over the top.



Biodiesel Kits - Biodiesel Processors

Friday, April 3rd, 2009
Boomer Sagacloud asked:


Heat is needed during the biodiesel conversion process for the following reasons:

1. Preheating your oil.

2. Heating your biodiesel during the settling process.

3. Drying water out of water-washed biodiesel.

4. Recovering methanol from biodiesel.

We have compiled a guide to heating systems here for you to be able to make a more informed decision on which system is best for you. If you have questions about any of this information call 1-800-679-1398. The three main types of heating systems offered today are: -Oil Preheating Systems. -In-Line Heating Systems. -In-Tank Heating Systems Oil preheating systems are a safe traditional method of pre-heating the oil prior to processing. The system conists of a steel drum with at least one thermostat controlled barrel heater and insulation. This is a very safe method because there are no heating elements in contact with the liquid. The standard Freedom Fueler comes with this type of heating system. In-Line Heating Systems Better For:

- Pre-heating your oil.

- Drying water-washed biodiesel Drawbacks:

- Requires a pump to operate.

- Cannot heat throughout entire process.

- Elements must be replaced periodically.

In-line heating systems are better than a pre-heating system but they have one common flaw, they all require a pump to circulate the oil through the heater in order for the heater to work. They are mainly intended to pre-heat the oil and dry the water out of biodiesel that has been water-washed. With an in-line heater using submerged elements, the user must remember to start the flow of liquid before turning the heater on.Note: All heaters have what is called a Watt Density. Watt density is the number of watts the heater puts out divided by the surface area of the heaters element. Our supplier of heating systems recommends no higher than 30 watts per square inch in the biodiesel process. All of our heaters have a watt density of 28 watts per square inch. In-Tank Heating Systems Best For:

- Preheating your oil.

- Heating biodiesel during settling.

- Drying water out of water-washed biodiesel.

- Removing methanol from dry-washed biodiesel.

An In-Tank Heating System is the ultimate in biodiesel heating systems, with the ability to maintain the batch temperature even if the temperature in your shop drops overnight. Home Biodiesel Kits is proud to offer the only In-Tank Heating System for home processors on the market. Each of our three Deluxe Biodiesel Processors now come with our new In-Tank Heating Systems. All three sizes come with sealed housings, a built in thermostat with high limit controls preset for the biodiesel process and an incoloy sheathed element to prevent corrosion. The entire unit is built into the top of the processor ensuring no leaks and a completely closed system. These heaters will allow you to heat your batch throughout the entire process and will maintain temperature with a built in sensor located in the center of the tank. Our custom heating units were designed and built specifically for our tanks and the biodiesel process with a watt density of 28. This is not an off the shelf product built for water or any other purpose but a professionally made heater manufactured by the leader in biodiesel heating systems. Call Jess or Ryan today to discuss our new In-Tank Heating Systems or to order one of our Deluxe Biodiesel Processors at 1-800-679-1398.If you want to read more about this on our blog click here to read about biodiesel



Biodiesel And It’s Many Uses

Wednesday, March 11th, 2009
Mike Boyd asked:


With gas prices increasing and growing environmental awareness, the need to consider alternate energy and fuel sources are becoming a necessity. One alternative is the use of Biodiesel fuel, which is becoming more and more popular today.

Because Biodiesel is a cleaner-burning diesel fuel, made from 100% natural, 100% renewable vegetable sources, its uses in today’s society may surprise you. Below are nine ways Biodiesel is being used. Some of which you may never have realized.

1) Biodiesel Car Rental - Yes that’s right. A Maui and Los Angeles car rental rents cars that run on Biodiesel. These cars get between 400 and 800 miles per tank! Not bad when consider the price of gas these days.

2) Home heating fuel - More people are taking a look at Biodiesel as an alternative for heating their home. Most oil-fired or boiler furnaces can use Biodiesel (B20), which is a fuel made of 80 percent traditional heating oil and 20 percent Biodiesel. Some people are getting their furnaces adapted to be able to burn B100, a fuel made entirely of vegetable oils, which burns much cleaner than traditional heating oil.

3) Electricity Generation - Diesel generators that produce electricity are now running on Biodiesel fuel. A superior alternative to the typical coal burning electricity generating plants currently being used in the United States. Running on Biodiesel is an inexpensive, clean and renewable way of creating electricity.

4) Trucking Industry - More and more truckers are switching from diesel fuel to Biodiesel fuel. The benefits are numerous not to mention the advantage of helping the environment and reducing our dependency on foreign oil, while saving money.

5) Agriculture - Not only a producer of Biodiesel, but also a consumer. Tractors, reapers, tillers, pickers, conveyors, generators, pumps, and irrigation systems which normally uses diesel fuel, now use Biodiesel to fuel their work, bringing agriculture full circle from producer to consumer.

6) Marine Vehicles - Commercial fleets such as ferries, recreational yachts, sailboats, and motor boats are all candidates for Biodiesel. For example Pacific Whale Foundation, located in Hawaii, use Biodiesel in their boats.

7) Tax Incentive - The IRS is offering tax incentives to anyone that produce and use Biodiesel fuel. The US Government is working to reduce greenhouse gas emissions by giving producers of Biodiesel fuel government funds. The tax incentive works to help tax paying customers by lowering the cost of the fuel bill.

8) Lubrication Additive - Because Biodiesel is a better lubricant than current low-sulfur petroleum, fuel injectors and other types of fuel pumps can rely on Biodiesel fuel for lubrication. With the right additives, engine performance can also be enhanced, making engines last longer. Other numerous applications can also make use of it’s lubricate properties, such as concrete forms and asphalt trucks. Its solvent properties also make it a safe parts cleaner, reducing skin and eye irritation associated with other cleaners.

9) Cleaner Environment - Biodiesel reduces carbon dioxide exhaust emissions by up to 80%. Because of this, Biodiesel has the potential to reduce air toxics and cancer causing compounds. Something we all can live with! If spilled, it will quickly degrade into natural organic residues, without polluting the environment.



Biodiesel Recipe

Wednesday, March 11th, 2009
Marlon Dirk asked:


Within this article, we are going to discuss the biodiesel recipe.

It isn’t any surprise that with the increasing cost of fuel, there appears to be a sincere interest within alternative fuels in order to help solve our environmental and energy problems. There are several individuals that have no choice but to drive their cars daily and they are searching for fuel options that are less expensive. If you were to ask the majority of individuals what two things they would like to have in a fuel, they would like the fuel to be inexpensive and they would also like for it to be green.

In case you are unaware of what green fuel means, it means that the fuel doesn’t harm the environment. Today, you will see a number of different fuel options that are being introduced and there are some of them that have proved to show really great results when it comes down to environmental friendliness and fuel economy. Biodiesel fuel is only one of the alternative fuels that are known to offer a realistic alternative fuel. However, the main problem with the biodiesel fuel is that it isn’t available all that many place quiet yet.

The Variety of Different Blends of Biodiesel Fuel

In the event that you are among the lucky ones that are able to locate biodiesel fuel nearby your home, you should know that the majority of the biodiesel fuel that is commercially available is blended. What this means is that in order to create it regular diesel and biodiesel have to be mixed together. Now you are probably wondering why they aren’t just using pure biodiesel? Well, unfortunately over time the rubber hoses and all of the other rubber parts are going to wear down and they are going to come into contact with the biodiesel on a regular basis. One of the ways that you are able to prevent this from happening is to mix some of the pure biodiesel with the regular diesel.

One hundred percent biodiesel is pure, which means that it isn’t mixed with the regular diesel. Biodiesel is produced for all of those individual that have made the necessary adjustments to their vehicles and taken out any of the rubber components that otherwise could be affected by the use of the biodiesel. However, unfortunately, there is a very small amount of individuals that are able to receive all of their benefits by using biodiesel because of the fact that there are several people that haven’t made all of the changes that are necessarily to their cars so that they are able to use pure biodiesel.

In the end, you will find the biodiesel recipe is made up out of pure biodiesel.



Nobody Has Yet Had Any Bad Experiences While Making Biodiesel

Tuesday, March 3rd, 2009
Muna wa Wanjiru asked:


The most convenient and cost effective option for the petroleum diesel is the conversion of oil into diesel. Nearly all the major European vehicle makers now provide their cars with warranties on the use of a pure Biodiesel. Now-a-days the people are making their own Biodiesel in their own home and the home brewing of Biodiesel is completely harmless as nobody has yet had any bad experiences while making Biodiesel.

For freshers, start with the unused or fresh vegetable oil. To prepare your own Biodiesel in your own home, you will need the following things:

* 1 litre of pure cooking oil;

* 250 ml of pure methanol;

* Either Sodium Hydroxide or Potassium Hydroxide;

* A blender;

* Weighing scales that are efficient in measuring upto 0.01 grams.

* 1 litre High Density polythene container;

* 2 bottles for settlingl;

* Duct tape; and

* Thermometer;

All the equipments must be clean and dry. The process of making Biodiesel is as follows:

First make sure that all the parts of the blender are in good condition. You must also check that the blender seals are tightly shut. And all the components are clean and dry. Heat the oil to 550 C and then pour the oil into the blender. Now carefully pour the sodium or potassium methoxide that is prepared from the high density polythene container into the blender. Now seal the lid of the blender and then blend the mixture carefully at low speed for 30 minutes while maintaining the speed and the temperature.

The moment the process is completed, you must pour the mixture carefully into a mini-processor. After the process is completed, allow the mixture to settle for 12 to 24 hours. You will find that the bottle in which the liquid is collected, there are two specific layers. One is yellow and the other is a dark coloured fluid which is glycerin and is a by-product. The upper layer is the Biodiesel. The color of the diesel depends upon the oil used but is generally pale color and is mostly yellow. The diesel might be cloudy or clear, which is not much of a problem. After setting it for some more time, it will clear out.

You must then take a wash test. If it passes through the wash test, then wash the rest of the Biodiesel.



Making Biodiesel at Home Could be as Easy as This

Wednesday, February 25th, 2009
Muna wa Wanjiru asked:


Biodiesel is a fuel or a type of diesel that is prepared from the degradation or processing of biodegradable material as substances. Biodiesel is a fuel that burns more efficiently than any other fuel and also burns more cleanly. The clean burning of the fuel also results in the low emission of harmful gasses, i.e. we get a better environment to live in. The biodiesel is the only unconventional fuel that is recommended by the American and the European Governments.

Biodiesel is quite easy to prepare and hence can be easily made at home. Making biodiesel at home is a lot more cost effective. For making biodiesel at home you will need the following materials.

1. First you will need a fresh cooking vegetable oil. For the biodiesel to be more cost effective you can use the cheapest oil that you can find

2. Then you will need the ‘Lye’ or the caustic soda. You will need approximately 5 grams of caustic soda. The caustic soda can be found anywhere. Most of the drains cleaning powders have it.

3. The third thing you will need is Methanol. You can find it in supply stores for the auto industry. It is usually found in the anti-freeze section.

4. Some of the other materials that you will require are one plastic bottle of 2 liter capacity which should be clean and dried.

5. A funnel that can fit in the neck of the bottle.

6. A washed and dried container for the blending of caustic soda and methanol. The container should be sealed so that not a drop of liquid comes out.

7. A measuring cup for measuring methanol.

8. Weight scales.

For the safe production of biodiesel, you must also have aprons, goggles or face shielding equipments and hand gloves.

The following is the method to prepare biodiesel at you home:

* Firstly you must choose a place that has proper ventilation, and warm the material at room temperature.

* Now put 250 ml of methanol into a jar and add about 5 grams of caustic soda or lye to methanol and seal the lid so that not a drop of liquid comes out.

* Blend the mixture at a low speed for upto 10 minutes. Do not panic if the temperature starts increasing.

* Now heat the vegetable oil at 1300F. Now put the oil in the plastic container with the help of the funnel. Do not overheat the oil.

* Now pour the mixture of lye and methanol which has now become sodium methoxide. Avoid breathing vapours. When the mixture is put into the oil, blend it for 15 to 20 minutes and then let the mixture settle.

After the mixture is settled for 20 minutes, you will see that two separate layers have formed in the bottle. The upper layer of liquid, which is visibly light coloured, is the biodiesel and the lower layer is the by-product glycerin. You can then pump out the biodiesel with the help of a handpump.
