Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.
The availability of biodiesel around the World is increasing. It is estimated that by 2010 the market for biodiesel will be 7.5 billion litres (2 billion USgallons) in the U.S and 9.5 billion litres (2.5 billion USgallons) in Europe. [16] Biodiesel currently has 3% of the diesel market in Germany and is the number 1 alternative fuel. [17]
The feedstock used to make the biodiesel fuel can significantly alter the resulting exhaust gas and particulate matter emissions, [66] [67] even when blended with commercial diesel fuel. [68] A study performed by the Chonbuk National University concluded that a B30 biodiesel blend reduced carbon monoxide emissions by approximately 83% and ...
Sugar- and starch-producing crops are used to make bioethanol, and oil-producing crops are used to make biodiesel. The United States is the largest producer of bioethanol, while the European Union is the largest producer of biodiesel. [23] The global production of bioethanol and biodiesel provides 2.2 and 1.5 EJ of energy per year, respectively ...
Bio-Blend Fuels Inc. is a company producing bio-diesel from various materials including beef tallow and vegetable oil. They are based in Manitowoc, Wisconsin and have an annual capacity of 2.6 million US gallons. The company is notable for producing bio-diesel from pig fat recovered from commercial bacon production facilities.
Biodiesel is a liquid fuel composed of vegetable oils and or animal fats. To create the gasoline itself, these subsequent liquids are combined with alcohol. Biodiesel is used to fuel compression ignition engines, otherwise known as diesel engines. The most common product of biodiesel is B20, a 20:80 blend: 20% biodiesel to 80% petroleum diesel.
If the vegetable oil is cleaned at home by the consumer, WVO can result in considerable savings. Many restaurants will receive a minimal amount for their used cooking oil, and processing to a biofuel is fairly simple and inexpensive. Making the oil into biodiesel involves some toxic and hazardous chemical transformations.
Production of oil/biodiesel from rape covers more than 12,000 km 2 in Germany alone, and has doubled in the past 15 years. [10] Typical yield of oil as pure biodiesel is 100,000 L/km 2 (68,000 US gal/sq mi; 57,000 imp gal/sq mi) or higher, making biodiesel crops economically attractive, provided sustainable crop rotations are used that are ...
