The commercial testresults indicate that the olefin content of catalyti-cally cracked gasoline can be significantlyreduced to less than 20 v%, while sulfur content reduced by 15%-25% and RON increased by 0.5―2units in a RFCC unit. In addition, propylene yield and the production ratio of diesel to gasolinecan also be remarkably enhanced in the RFCC unit.展开更多
