Abstract
A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant oils and animal oils, fats, and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating i.e. decarboxylating, decarbonylating, and/or hydrodeoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel or diesel boiling range fuel blending component. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties. A portion of the hydrogenated and deoxygenated feedstock is selectively separated and then recycled to the treatment zone to increase the hydrogen solubility of the reaction mixture.
