Abstract
A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant and animal fats and oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel. Water is added to the deoxygenation reaction to drive carbon monoxide and water to react to form hydrogen and carbon dioxide. The hydrogen is then consumed by the reactions. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties.
