1. A process for producing a renewable hydrocarbon fuel product, the process comprising:
hydrotreating used cooking oil to produce a renewable paraffinic intermediate comprising at least 80% C8-C20 hydrocarbons and substantially free of aromatics;
reacting said renewable paraffinic intermediate in a fluid catalytic cracking reactor at a temperature ranging from 400° C. to 550° C., and a catalyst to renewable paraffinic intermediate feed ratio from 4:1 to 10:1 to produce a renewable hydrocarbon fuel product comprising less than 5% coke;
wherein said renewable paraffinic intermediate comprises 0% to 10% by volume of a petroleum feed,
wherein said renewable paraffinic intermediate being fed to the reaction zone has not isomerized; and
wherein the used cooking oil is pre-treated prior to hydrotreating, and wherein pre-treatment consists of degumming and bleaching.
