裂解汽油二段加氢催化剂LY-9802的工业应用

摘要

LY-9802 was applied in a newly built 2nd stage pyrolysis gasoline hydrogenation unit in a large-scale jointly invested petrochemical enterprise.Result showed that the first regeneration cycle was 31 months.Under the inlet temperature of 225-241℃,pressure of 2.67MPa,raw rate of 33-48 t/h,sulfur content of hydrogenation production is less than 0.2mg/kg,BrV is less than 0.1gBr/100g.After regeneration,the catalyst has run stably for 3 month so far.Under the inlet temperature of 248 ℃,pressure of 2.67MPa,raw rate of 46t/h,sulfur content of hydrogenation production is less than 0.2mg/kg,BrV is less than 0.1gBr/100g.%2009年,LY-9802催化剂作为国内一家大型合资石油化工企业的新建裂解汽油加氢装置的首装剂投入使用。运行结果表明,该催化剂第一运行周期为31个月,在入口温度为225～241℃、压力为2.67 MPa、进料量为33～48 t/h的条件下,硫含量小于0.2 mg/kg,溴价小于0.1 gBr/100g;经过再生处理后,该催化剂已稳定运转3个月,在入口温度为248℃、压力为2.67 MPa、进料量为46 t/h的条件下,硫含量小于0.2 mg/kg,溴价小于0.1 gBr/100g。
