Abstract
A process for producing olefins from biorenewable feedstocks has been developed. The process comprises first pretreating the feedstock, e.g. vegetable oil, to remove contaminants such as alkali metals and then cracking the purified feedstock in a fluidized catalytic cracking (FCC) zone operated at conditions to provide C.sub.2-C.sub.5 olefins.
