重油裂化催化剂混兑应用工业试验

MIXED CATALYST OPERATION IN RESID FCCU

介绍了大连石化公司ＲＦＣＣＵ在使用超稳氢Ｙ型ＬＣＳ－７剂的基础上混兑一定比例的超稳Ｙ型ＬＣＨ－７或ＬＣＯ－７剂的工业运转情况。使用混兑催化剂可提高渣油掺炼比，降低焦炭产率，提高装置处理量，并可提高汽油辛烷值。

The operation of USY type LCH-7 or LCO-7 catalyst mixed with the originally used USHY type LCS-7 catalyst in the resid FCCU in Dalian Petrochemical Company is introduced. Increases in throughput, resid blending ratio and gasoline octane as well as drop in coke yield can be obtained after the catalyst mixing.
