Patent ID: 7511181

Claim:
A process for producing a hydrocarbon fraction from a biorenewable feedstock comprising pre-treating the feedstock in a pretreatment zone at pretreatment conditions to remove at least a portion of contaminants in the feedstock and produce a first effluent stream; reacting the first effluent stream in a reaction zone by contacting the first effluent stream with a catalyst at reaction conditions comprising a temperature of about 200Â° C. to about 300Â° C., a hydrogen partial pressure of about 1034 kPa (150 psi) to less than 2000 kPa (290 psi) and a liquid hourly space velocity of about 0.5 hr âˆ’1 to about 2 hr âˆ’1 thereby hydrogenating and deoxygenating the first effluent stream to provide a reaction product comprising a hydrocarbon fraction comprising n-paraffins.
