PRODUCTION OF TRANSPORTATION FUEL FROM RENEWABLE FEEDSTOCKS

摘要

Disclosed herein is a process for producing a diesel boiling point range product and an aviation boiling point range product from renewable feedstocks such as plant and animal oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating (4) to provide a hydrocarbon fraction (12) which is then isomerized and selectively cracked (22) to form the diesel boiling point range product (46) and the aviation boiling point range product (45). A portion of the diesel boiling point range product (46), aviation boiling point range product (45), naphtha product (52), LPG (50), or any combination thereof can be optionally used as a rectification agent in the selective hot high pressure hydrogen stripper (8) to decrease the amount of product carried in the stripper overhead (14).
