PRODUCTION OF RENEWABLE DIESEL AND PROPYLENE

摘要

Feeds containing triglycerides are processed to produce a diesel fuel product and propylene. The diesel product and propylene are generated by deoxygenating the triglyceride-containing feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyceride-containing feed is processed in the presence of a catalyst containing a Group VI metal and a Group VIII non-noble metal and in the presence of CO.

主权项

1. A method for processing a biocomponent feedstock, comprising:
exposing a feedstock, the feedstock comprising at least 40 wt % of a biocomponent feed containing triglycerides, to a first catalyst in the presence of hydrogen and at least 300 vppm of CO under first effective deoxygenation conditions for forming an at least partially deoxygenated effluent, the first catalyst comprising a Group VI metal and a Group VIII non-noble metal, the at least partially deoxygenated effluent having an oxygen content that is at least 40% less than an oxygen content of the feedstock; separating the at least partially deoxygenated effluent to form a gas phase effluent comprising propylene and a liquid phase effluent; and separating at least a portion of the propylene from the gas phase effluent.
