摘　　要：以Ni和Mo为活性组分,Al2O3为载体,制备了氧化型Ni-Mo/Al2O3催化剂O-1,在此基础上,以自制的水溶性复合硫化物为硫化剂,制备了器外预硫化型Ni-Mo/Al2O3催化剂S-1,通过BET、XRD和HRTEM等手段对2种催化剂的物化性质做了表征,并对比考察了催化剂对劣质石脑油加氢脱硫脱氮的性能。结果表明:器外预硫化型催化剂对劣质石脑油加氢脱硫脱氮的性能与氧化型催化剂接近,其加氢石脑油产品的硫氮含量均低于0.5μg/g,这说明采用水溶性复合硫化物为硫化剂可以对氧化型催化剂进行有效地器外预硫化。The oxidized Ni-Mo/Al2O3 catalyst O-1 was prepared by using Ni and Mo as active components and Al2O3 as support.On this basis,a self-made water-soluble composite sulfide was used as vulcanizing agent to prepare the ex-situ presulfurization Ni-Mo/Al2O3 catalyst S-1.The physicochemical properties of the two catalysts were characterized by BET,XRD and HRTEM.The performance of the catalyst for hydrodesulfurization and hydrodenitrogenation of inferior naphtha was investigated.Results showed that the performance of the ex-situ presulfurization catalyst on the hydrodesulfurization and hydrodenitrogenation of inferior naphtha was close to that of the oxidized catalyst,and the sulfur and nitrogen contents of hydrogenated naphtha products were less than 0.5μg/g.The oxidized catalyst can be effectively pre-vulcanized by using a wa ter-soluble composite sulfide as a vulcanizing agent.
