Abstract: 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.
