Patent ID: 7982075

Claim:
A process for producing a paraffin-rich diesel product from a renewable feedstock comprising treating the feedstock in a first reaction zone by hydrogenating and deoxygenating the feedstock using a catalyst at reaction conditions in the presence of hydrogen and at least one sulfur containing component in an amount greater than 1000 wt.-ppm sulfur, measured as elemental sulfur, to provide a first reaction zone product stream comprising hydrogen, carbon dioxide, and a hydrocarbon fraction comprising paraffins having from about 8 to about 24 carbon atoms; separating, in a hot high pressure hydrogen stripper, a gaseous stream comprising hydrogen and at least a portion of the water and carbon oxides from the first reaction zone product stream and a remainder stream comprising at least the n-paraffins from the first reaction zone product stream; introducing the remainder stream to a second reaction zone to contact an isomerization catalyst at isomerization conditions to isomerize at least a portion of the paraffins and generate a branched paraffin-rich stream.
