This articles refers to the development of the technology for hydrodesulfurization(HDS)andaromatization of FCC naphtha This technology adopts a catalyst with aromatization performance,whichdoes not reduce the octane rating of gasoline in the course of HDS of FCC naphtha.Experimental resultshave shown that the sulfur removal rate of FCC naphtha could reach over 85%,with the RON of gasolineincreased by 0.2—0.6 units,the MON increased by 1.3—1.8 units and the antiknock index of the gasolineincreased by around one unit.The total C_5~+ liquid yield was over 95%.The activity of regenerated catalystcould be restored to be equal to that of fresh one after coke burning on the spent catalyst.
