Does soybean oil convert to biodiesel?

Approximately one-half of the input fossil energy is associated with the conversion of soybean oil to biodiesel. As crop yields increase and production technology improves, the energy inputs should decrease and the energy ratio should increase over time. Table 16.2. Fossil Energy Requirements for the Biodiesel Life Cycle

Can soybean oil be used as fuel?

Higher petroleum prices and government incentives have produced conditions where soybean oil can be used as fuel, usually in the form of biodiesel. A general equation for the gross heat of combustion of vegetable oils developed by Bertram (1946) is: - ¦¤ H C ( cal / g) = 11, 380 - ( IV) - 9.15 ( SV)

Is soybean oil a good source of energy?

This is still one of the most concentrated sources of energy found in nature. Soybean oil can be burned directly for heat, although it is rare to do so because it is more expensive than other traditional heating fuels such as natural gas, heavy fuel oil or coal. Transportation fuels tend to be in shortest supply and command high prices.

How is soybean oil extracted?

While most soybean oil is extracted in solvent extraction plants using hexanes as the solvent, there has been considerable interest from biodiesel producers in using expeller-extracted oils, sometimes known as mechanical extraction or screw pressing.
