Pure biodiesel has the highest BTU content of any alternative fuel. It also has the highest energy balance of any fuel. For every unit of fossil energy needed to produce biodiesel, more than 3 units of energy are gained. As for gasoline and diesel, every one unit put in yields only about one half unit.
As a domestically-produced fuel, biodiesel can reduce the need for fossil fuel and improve the nation’s energy security.
Biodiesel is registered as a fuel and fuel additive with the EPA and meets clean diesel standards established by the California Air Resources Board (CARB). B100 (100 percent biodiesel) has been designated as an alternative fuel by the U.S. Department of Energy and the U.S. Department of Transportation.
Biodiesel is used as a diesel substitute for road transport vehicles.
It can be produced using either chemical or physical production routes, with either waste or virgin cooking oil.
Chemical production uses a process called trans-esterification.
Biodiesel can be used in cars that take diesel, heavy transport such as trucks, machinery, construction equipment, ships and most things that take diesel.
To produce the biodiesel, the esters in the oil vegetable are separated from the glycerin. The esters are the basis of the biodiesel. During the process, the glycerin is substituted by the ethanol, turning to ethanol or methanol. We grant preference to the ethanol for being less aggressive than the methanol.
The process of transformation of the vegetable oil in biodiesel is called TRANSESTERIFICATION.
Biodiesel is not raw vegetable oil. Fuel-grade biodiesel must be produced to strict industry specifications (ASTM D6751) in order to ensure proper performance.
Biodiesel is a biodegradable and non-toxic alternative fuel produced from new or used vegetable oil that is produced from renewable resources. It can be used in any Diesel engine without modification.
Rudolf Diesel, the inventor of the diesel engine, created the engine to be powered by peanut and other vegetable oil. That was in the late 1800s before cheaper petroleum-based diesel fuel (petrodiesel) became widely available.
