ABSTRACT:
An integrated process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant and animal fats and oils and using a byproduct naphtha as a denaturant for ethanol. 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 fuel or diesel boiling range fuel blending component. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties. A byproduct naphtha stream from the diesel boiling range fuel production process is used as the denaturant in an alcohol denaturing process for the generation of denaturized ethanol.
