Abstract: A method of producing a hydrocarbon product by hydrotreating a feedstock comprising triacylglyceride (TAG) 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, 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.

Abstract: A process of preparing lignite (low rank) coal filter material, suitable for use in lieu of more expensive activated carbon filter materials, is disclosed. The process comprises size reducing Leonardite coal material to a suitable filtering effective size, and thereafter heating the size reduced Leonardite preferably to at least 750.degree. C. in the presence of a flow of an inert gas.
