Patent ID: 7626063

Claim:
A process for producing C10-C30 hydrocarbons comprising: (a) contacting i) a fluid comprising at least one fatty material and at least one feed hydrocarbon, and ii) hydrogen with a catalyst in a reaction vessel under conditions sufficient for converting at least a portion of said at least one fatty material into one or more C10-C30 hydrocarbons and propane; (b) separating at least a portion of said propane from said one or more C10-C30 hydrocarbons; (c) generating hydrogen from said separated portion of propane in step (b); and (d) recycling said generated hydrogen from step (c) to said reaction vessel of step (a), wherein said at least one fatty material is selected from the group consisting of triglycerides, dialycerides, monoalycerides, and free fatty acids, wherein said at least one feed hydrocarbon having a boiling point of between about 80° F. to about 1000° F., and wherein step (c) generates at least about 50% of the hydrogen required by step (a).
