Abstract
A method of producing a hydrocarbon product by hydrotreating a feedstock comprising triacylglyceride (TAG) and TAG-derived materials such as free fatty acid (FFA) and fatty acid methyl ester (FAME) in the presence of a nonsulfided hydrotreating catalyst to produce a first product comprising hydrocarbons. A method of producing a transportation fuel by selecting an undoped feedstock comprising virgin TAG, used TAG, FFA, and FAME or a combination thereof; hydrotreating the undoped feedstock in the presence of an unsulfided hydrotreating catalyst to produce a first product and subjecting the first product to at least one process selected from aromatization, cyclization, and isomerization to produce a second hydrocarbon product selected from gasoline, kerosene, jet fuel, and diesel fuels. A method is described by which fatty acids may be converted to hydrocarbons suitable for use as liquid transportation fuels. Additionally, the method allows for the blending of fatty acids with TAGs, and the conversion of such blends to hydrocarbons suitable for use as liquid transportation fuels. The method utilizes a catalyst and hydrogen as reductant to convert fatty acids to hydrocarbons. Subsequent steps, including dewatering, isomerization, and distillation, can provide a hydrocarbon mixture useful as a liquid transportation fuel or as a blendstock with petroleum transportation fuels.
