Basic research of adsorptive desulfurization was carried out concerning the high total sulfur concentration of C4hydrocarbon which was the reason for exceeding total sulfur concentration of MTBE. Based on the screening of active components, Cu (II)-Ce (IV) bimetal ion-exchanged 13X zeolites were prepared. Desulfurization performance of 13X zeolites modified with different metals was investigated by using model C4hydrocarbon which contained dimethyl disulfide (DMDS), dimethyl sulfide (DMS), and tert-butyl mercaptan (TBM). The Cu (II)-Ce (IV)/13X zeolites exhibited better desulfurization performance for C4hydrocarbon due to the formation of sulfur-metal (S-M) bond between metal and sulfur compounds.
