When was biodiesel first used?

Biodiesel FAQ : MetaEfficient
Transesterification was conducted as early as 1853. Rudolf Diesel designed this engine to run on vegetable oil. He did a demonstration at the 1900 World's Fair where he ran his engine on peanut oil. One of the first uses of biodiesel (transesterified vegetable oil) was powering heavy vehicles in South Africa before World War II.

Biodiesel - Frequently Asked Questions
Biodiesel can be used in any internal combustion diesel engine. Biodiesel can either be used in its pure form known as B100, or it can be mixed at any level with regular petroleum diesel. Some common mixtures are 20% biodiesel with 80% petro-diesel (B20) and 5% biodiesel with 95% petro-diesel (B5).

Biodiesel.org - Home Heating Oil
Biodiesel is a clean burning alternative fuel produced from vegetable oils and animal fats through a chemical reaction and meeting ASTM D 6751. Biodiesel contains no petroleum, but it can be blended at any level with heating oil. It can be used in home heating oil systems safely with no modifications to the fuel tanks, pumps or burners in concentrations up to 20% biodiesel with only minimal precautions (see conditions for use section).

Can Biodiesel be used in any diesel engine?

Earth Biofuels, Biodiesel Fuel Alternative, How to Make Biod...
Biodiesel can be used in any diesel engine, typically with no modifications to the engine necessary. It performs comparably to diesel, with similar BTU content and higher cetane. It offers excellent lubricity and lower emissions compared to petroleum diesel. The efficiency of diesel engines is the same whether using biodiesel, diesel, or biodiesel blends so differences in horsepower, torque or fuel economy are due entirely to volumetric energy content.

FAQ - Carbon Calculator - Cloud Amber
Biodiesel is a renewable fuel that is produced from the oil of crops including oilseed rape, sunflowers and soybeans, as well as from waste cooking oils. Diesel is sold as EN 590, which can contain a blend of 5% biodiesel and 95% ultra-low sulphur diesel. Biodiesel benefits the environment as follows: Because the crops used to make biodiesel take in carbon dioxide when they grow, biodiesel is considered a renewable fuel. It gives a 60% reduction in CO2 well to wheel.

Biomass Program: Biomass FAQs
Biodiesel is a clean burning alternative fuel produced from domestic, renewable resources such as new and used vegetable oils and animal fats. Biodiesel is primarily produced through base catalyzed transesterification. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics. Biodiesel can be blended at any level with petroleum diesel. For more information please visit, U.S. Department of Energy Alternative Fuel Data Center or National Biodiesel Board.

Can biodiesel be used for oil furnaces?

FAQ - GoBiodiesel
Yes. You can safely use B20 in an oil furnace. We do know people using B100 (100% biodiesel) in their home heating systems without any modifications. You can get B100 delivered for your oil furnace, just check our [Biodiesel Sources] page. If your oil tank is in good condition it should store well.

What ingredients are used in the Biodiesel manufacturing process?

Freedom Fuel America
No. The lye is easy to find at your local hardware store, usually under the plumbing supplies section. It is commonly used as a drain opener. Look for 100% pure, undiluted lye. Do NOT purchase liquid lye. Lye granules or flakes can sometimes be purchased in bulk, but care must be taken in storage to keep it dry at all times. Lye is corrosive. Avoid contact with skin. Wear eye protection when handling lye. Follow all safety precautions on the product label.

What types of oil can be used to make Biodiesel?

Freedom Fuel America
Biodiesel can be made from ALL types of vegetable and animal oil, but oil that is from animal sources (tallow, lard, grease, etc.) needs special conditions and procedures to process it successfully. All vegetable oils can be used, including all seed oils, nut oils (including peanut oil), bean oils (including soybean oil), olive oils, and oil pressed from algae. Biodiesel can be made from new or used oil.

Is it easy to get used oil to make Biodiesel with?

Freedom Fuel America
You could have difficulty finding oil to use for making Biodiesel. Used cooking oil is a marketable commodity, and in some areas, it is actively being used as such. Do not assume that you will be able to get oil just because your area has many fast-food restaurants. You should get out into your local area, and locate your oil sources early in your research process. Finding adequate or affordable oil supplies can be the most challenging part of making Biodiesel in some areas.

Biodiesel is a biodegradable clean-burning alternative fuel, produced from renewable resources, such as soy beans or used vegetable oils. Pure biodiesel contains no petroleum yet it can be blended at any level with petroleum diesel to create blends, the most commonly used being B20. BioDiesel is one of the most thoroughly tested alternative fuels on the market. Studies show that it performs similar to conventional petroleum-based fuels while benefiting the environment and human health.

Greenleaf Biofuels: FAQs
Biodiesel is refined from vegetable oils through a fairly simple chemical reaction called transesterification. Vegetable oils primarily consist of triglycerides: three carbon chains connected by a glycerin molecule. In the reaction process, an alcohol (methanol or ethanol) is used with a catalyst (potassium or sodium hydroxide) to separate the glycerin molecule from the carbon chains. The long carbon chains in biodiesel have a very similar profile to petroleum middle distillates.

Minnesota Soybean - Frequently Asked Questions
Biodiesel is a clean burning fuel for diesel engines made from domestically produced, renewable fats and oils such as soybean oil. Biodiesel has no sulfur or aromatic compounds and already meets the new Environmental Protection Agency (EPA) ultra low sulfur diesel fuel mandated for introduction in 2006. Biodiesel can be used in existing diesel engines without modification. Biodiesel burns substantially cleaner than petroleum based diesel fuel.

Biodiesel is a clean-burning alternative fuel, produced from domestic, renewable resources, such as soybeans or used vegetable oils. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create blends, generally called B20 or B5. In addition to supporting domestic farmers for their soybean crops, a primary reason for developing alternatives to oil is the creation of U.S. independence from foreign oil.

Biodiesel FAQ : MetaEfficient
No Engine Conversions. Biodiesel runs in any conventional, unmodified diesel engine. No engine modifications are necessary to use biodiesel and there is no �engine conversion.� In other words, �you just pour it into the fuel tank.� Lubricates Engines. Biodiesel is more lubricating than diesel fuel, it increases the engine life and it can be used to replace sulfur, a lubricating agent that, when burned, produces sulfur dioxide - the primary component in acid rain.

Can Biodiesel be used as a fuel lubricity additive?

Biodiesel - Community Fuels - Makes Sense
Testing has confirmed that biodiesel can provide sufficient levels of fuel lubricity, even at blend levels below 1%, in current on-road diesel fuel. Testing is underway to determine specific blend levels that would be required in ultra-low sulfur diesel fuel (15 ppm). Replenishing the loss lubricity that will be apparent in future diesel fuel can be accomplished with conventional lubricity additives either on the market today or in the process of being formulated.
