Renewable fuels, diesel and methods of generation from renewable oil sources

Abstract

A process for the generation of renewable fuel and/or biofuel from a renewable oil feedstock having a high free fatty acid content. The renewable oil feedstock can be renewable plant oil or renewable animal fat or oil, including renewable corn oil recovered from a by-product of ethanol production, such as distillers corn oil and/or corn oil solvent extracted from distillers dried grains with solubles (DDGS) and/or distillers dried grains (DDG). The free fatty acid content of the renewable oil feedstock can be reduced by a glycerolysis process in the presence of a molar excess of glycerin to provide an adequate resulting feedstock having a reduced free fatty acid content. The resulting feedstock capable of being subjected to further processing for the generation of renewable fuel and/or biofuel.
