Abstract: Systems and methods of producing olefins via catalytic cracking are disclosed. Hydrocarbons of a naphtha stream are isomerized by converting straight chain Cn hydrocarbons to branched Cn hydrocarbons, thereby forming an isomerized naphtha stream. The isomerized naphtha stream is subsequently fed to a catalytic cracking unit such that the hydrocarbons of the isomerized naphtha stream form olefins. In the catalytic cracking process, the reaction temperature can be kept lower than 680° C., thereby increasing the reactivity and minimizing catalyst deactivation in the catalytic cracking process.
