摘　　要：介绍了一种自主研发的预还原-钝化-预硫化型裂解汽油一段镍基LY-2008催化剂,及其制备和器外硫化工艺研究。该催化剂在抚顺石化和四川石化新建的80万t/a乙烯装置首次工业应用情况表明,催化剂具有优异的加氢和抗砷中毒能力。这标志着国产镍基催化剂在大型乙烯配套裂解汽油加氢装置工业应用迈出了坚实的一步,为实现LY-2008催化剂大规模的推广应用奠定了良好的基础。This paper introduces a self-developed prereduction-passivation-presulfuration pyrolysis gasoline first stage hydrogenation LY-2008 catalyst,its preparation and external pre-sulfuration process. The results of its first time application on the new 800 kt/a ethylene plant in Petro China Sichuan Petrochemical Company show that this catalyst has excellent hydrogenation ability and arsenic poisoning resistance. This marks China-made nickel catalyst has taken a big step forward in the application of the matched pyrolysis gasoline hydrogenation facility in large scale ethylene cracker,which lays a good foundation to achieve wider application of LY-2008 catalyst.
