PERFORMANCES OF CATALYST FOR GASOLINE DESULFURIZATION VIA CATALYTIC CRACKING

Desulfurization of gasoline via catalytic cracking is a brand\|new technology. A kind of catalyst for catalytic cracking gasoline is developed. The catalyst is evaluated with micro\|reactor and fluid\|bed reactor apparatus. The results show that the catalyst has very good desulfurizing activity and cracking selectivity to sulfides. For different gasoline,more than 50% sulfides can be removed with minimum cracking loss of gasoline. Furthermore,after cracking desulfurization, olefin content decreases, but iso\|alkane and aromatic hydrocarbon contents increase, so octane number of the desulfurized gasoline may increase in some extent.
