The fluid catalytic cracker (FCC) is the primary conversion unit in most refineries.About 45% of worldwide gasoline proiuctions come either directly from FCC units or indirectly from combination with downstream units[1].In commercial FCC unit,feed oil is introduced into the riser reactor through FCC nozzles;the goal is to ideally contact the feed oil with catalysts in the riser under optimal operating conditions for a maximum yield in gasoline, LPG and diesel.
