11 Facts About Biodiesel

Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters.

Biodiesel contains virtually no sulfur and although lacking sulfur compounds in as in petrodiesel that provide much of the lubricity, it has promising lubricating properties and cetane ratings compared to low sulfur diesel fuels and often used as an additive to ultra-low-sulfur diesel fuel to aid with lubrication.

Biodiesel has different solvent properties from petrodiesel, and will degrade natural rubber gaskets and hoses in vehicles, although these tend to wear out naturally and most likely will have already been replaced with FKM, which is nonreactive to biodiesel.

Biodiesel has been known to break down deposits of residue in the fuel lines where petrodiesel has been used.

Biodiesel can be used as a heating fuel in domestic and commercial boilers, a mix of heating oil and biofuel which is standardized and taxed slightly differently from diesel fuel used for transportation.

Biodiesel has displayed its capacity to significantly dissolve crude oil, depending on the source of the fatty acids.

Biodiesel is an effective solvent to oil due to its methyl ester component, which considerably lowers the viscosity of the crude oil.

Biodiesel is commonly produced by the transesterification of the vegetable oil or animal fat feedstock, and other non-edible raw materials such as frying oil, etc.

NFESC, with Santa Barbara-based Biodiesel Industries is working to develop biodiesel technologies for the US navy and military, one of the largest diesel fuel users in the world.

Biodiesel is a much better lubricant compared with fossil petroleum diesel due to the presence of esters.

Biodiesel has higher brake-specific fuel consumption compared to diesel, which means more biodiesel fuel consumption is required for the same torque.
