  • Patent number: 10144881
    Abstract: A process for converting triacylglycerides-containing oils into crude oil precursors and/or distillate hydrocarbon fuels is disclosed. The process may include: reacting a triacylglycerides-containing oil-water-hydrogen mixture at a temperature in the range from about 250° C. to about 525° C. and a pressure greater than about 75 bar to convert at least a portion of the triacylglycerides and recovering a reaction effluent comprising water and one or more of isoolefins, isoparaffins, cycloolefins, cycloparaffins, and aromatics; hydrotreating the reaction effluent to form a hydrotreated effluent.

  • Patent number: 10144880
    Abstract: A process for converting triacylglycerides-containing oils into crude oil precursors and/or distillate hydrocarbon fuels is disclosed. The process may include: reacting a triacylglycerides-containing oil-water-diatomic hydrogen mixture at a temperature in the range from about 250° C. to about 560° C. and a pressure greater than about 75 bar to convert at least a portion of the triacylglycerides and recovering a reaction effluent comprising water and one or more of isoolefins, isoparaffins, cycloolefins, cycloparaffins, and aromatics; and hydrotreating the reaction effluent to form a hydrotreated effluent.

  • Patent number: 7691159
    Abstract: A triglyceride-to-fuel conversion process including the steps of (a) preconditioning unsaturated triglycerides by catalytic conjugation, cyclization, and cross-link steps; (b) contacting the modified triglycerides with hot-compressed water containing a catalyst, wherein cracking, hydrolysis, decarboxylation, dehydration, aromatization, or isomerization, or any combination thereof, of the modified triglycerides produce a crude hydrocarbon oil and an aqueous phase containing glycerol and lower molecular weight molecules, and (c) refining the crude hydrocarbon oil to produce various grades of biofuels.
