摘　　要：考察了硫化物对裂解汽油一段加氢催化剂LY-2008加氢性能的影响,并对催化剂失活机理进行了分析。结果表明:在含硫量为30μg/g的条件下,除二硫化碳以外,二甲基二硫醚、丁硫醇、二甲基硫醚、噻吩对催化剂LY-2008共轭烯烃加氢性能的影响很小;5种硫化物对催化剂LY-2008单烯烃加氢性能的毒性由大到小依次为:二甲基二硫醚,丁硫醇,二硫化碳,二甲基硫醚,噻吩;催化剂LY-2008对二硫化碳的最大耐受量为50μg/g;二硫化碳是引起催化剂LY-2008上共轭烯烃加氢失活的主要原因。The effect of sulfides on the hydrogenation performance of catalyst LY-2008 for pyrolysis gasoline one-stage hydrogenation was investigated,and the deactivation mechanism was analyzed.The results showed that dimethyl disulfide,butyl mercaptan,dimethyl sulfide,thiophene except carbon disulfide had very little effect on dienes hydrogenation.The poisoning of the five sulfides for olefin hydrogenation was as follows:dimethyl disulfide,butyl mercaptan,carbon disulfide,dimethyl sulfide,thiophene.The maximum tolerance of carbon disulfide was 50μg/g,carbon disulfide was the main deactivation reason of dienes hydrogenation on catalyst LY-2008.
