镍基裂解汽油加氢催化剂LY-2008的工业应用

Industrial application of Nickel based catalyst LY-2008 in pyrolysis gasoline hydrogenation

在中国石油独山子石化公司裂解汽油一段加氢装置上进行了LY-2008催化剂的工业应用。结果表明，LY-2008在反应器人口温度为40～87℃，压力为2．6～2．7MPa，新鲜油空速为1．5～2．8h，进料量为15～21m^3／h，循环比（体积比）为2．47～7．00的操作条件下，连续运行6个月产品中苯乙烯质量分数小于1．5％，可达到指标要求。在空速稍高的条件下运转，LY-2008催化剂的入1：3温度和产品苯乙烯均低于HTC-200，表明LY-2008的活性和选择性优于HTC-200。

Nickel based catalyst LY -2008 was applied in the first stage of pyrolysis gasoline hydrogenation unit of Dushanzi Petrochemical Company. The results showed that after running for 6 months at the condition of inlet temperature 40 - 87℃, reaction pressure 2.6 - 2.7 MPa, fresh oil space velocity 1.5 - 2.8 h^-1 , the mass fraction of styrene in hydrogenation product was less than 1.5%.At the condition of higher fresh oil space velocity, the inlet temperature and the mass fraction of styrene in production applied LY -2008 were both lower than HTC - 200, showing activity and selectivity of LY- 2008 was superior to HTC -200.
