Fluid catalytic cracking process employing a lipid-containing feedstock

A method for making a fuel comprising:

• coprocessing, in a fluid catalytic cracking unit, a petroleum-derived feedstock with up to 50 wt. %, based on the total weight of the feedstocks, of a lipid-containing feedstock in the presence of a catalyst under fluidized catalytic cracking conditions to obtain the fuel;
• wherein the fluid catalytic cracking unit comprises a riser reactor and a stripper;
• wherein the petroleum-derived feedstock is injected into the fluid catalytic cracking unit at a first injection point, and the lipid-containing feedstock is injected into the fluid catalytic cracking unit at a second injection point, separate from the first injection point, and wherein the second injection point flows into the stripper;
• and
• wherein the lipid-containing feedstock is contacted with the catalyst in the stripper under fluidized catalyst cracking conditions comprising a temperature of from about 880° F. to about 1000° F., at a pressure from about 14 psia to about 40 psia, and for a time period ranging from about 30 second to about 5 minutes.
