摘要： Disclosed herein is a method for making diesel, gasoline and LPG comprising coprocessing a petroleum-derived feedstock with up to 50 wt. %, relative to the total weight of the feedstocks, of a lipid-containing feedstock in the presence of a catalyst under fluidized catalyst cracking conditions. Also disclosed herein is a method for making a diesel fuel or a combined diesel and gasoline fuel by injecting up to 50 wt. %, relative to the total weight of the feedstocks, of a lipid-containing feedstock to a stripper or a riser quench downstream from a petroleum derived feedstock injection point in a fluid catalytic cracking unit.

摘要： A process is provided for upgrading a renewable feedstock. The process includes introducing the renewable feedstock into a fluid catalytic cracking (FCC) reactor unit operating under catalytic cracking conditions and comprising a circulating inventory of an equilibrium catalyst composition; removing a portion of the equilibrium catalyst inventory from the FCC reactor unit while replacing all the equilibrium catalyst removed from the unit with a spent catalyst to obtain a composite circulating catalyst within the FCC reactor unit; and contacting the composite circulating catalyst with the renewable feedstock in the FCC reactor unit under a steady state environment to provide a product stream comprising cracked products.
