Patent ID: 8198492

Claim:
A process for producing a diesel boiling point range product and an aviation boiling point range product from a renewable feedstock comprising; a) treating the feedstock in a first reaction zone by hydrogenating and deoxygenating the renewable feedstock using a catalyst at reaction conditions in the presence of hydrogen to provide a first reaction zone product stream comprising hydrogen, water, carbon dioxide, and a hydrocarbon fraction comprising paraffins in the diesel boiling point range and in the aviation boiling point range; and b) selectively separating, in a hot high pressure hydrogen stripper, a gaseous stream comprising at least a portion of the hydrogen, water, and carbon oxides from the first reaction zone product stream and a remainder stream comprising at least the paraffins; c) introducing the remainder stream to a second reaction zone to contact an isomerization and selective hydrocracking catalyst at isomerization and selective cracking conditions to selectively hydrocrack at least a portion of the paraffins and to isomerize at least a portion of the paraffins and generate a branched paraffin-enriched stream; d) cooling the branched paraffin-enriched stream and the gaseous stream and separating a gaseous component comprising at least hydrogen and carbon dioxide from a liquid hydrocarbon component and a water component; e) separating the liquid hydrocarbon component into an overhead stream, a diesel boiling point range product, and an aviation boiling point range product.
