摘要
本文对引进重整催化剂和几种国产催化剂在工业运转中进行了综合比较，结果表明，国产ＣＢ－７和ＣＢ－８催化剂在三苯产率上分别达到４６．３１％和４７．１５％，超过进口的Ｒ－３２催化剂（扬子为４０．９７％，上海为４１．５０％），并且达到进口的Ｅ—８０３催化剂的三苯产率（辽阳为４７．３８％，天津为４５．８０％），说明ＣＢ－７和ＣＢ－８催化剂在三苯上的活性和选择性已超过Ｒ－３２催化剂，达到Ｅ－８０３催化剂的水平。ＣＢ－７催化剂连续运转７０８天没有再生，运转末期其脱戊烷油收率和芳烃产率没有发生明显减少，说明在稳定性上已超过Ｅ－８０３催化剂。
Abstract The industrial performance of two imported catalysts and two demestic reforming catalysts are presented and comprehensively compared. It shows that the BTX yield of domestic CB-7 and CB8 catalysts (46.31 % and 47.15% respectively) has exceeded that of imported R-32 catalyst (40.97% at Yangzhi,41.50% at Shangai) and reached that of imported E-803 catalyst (47.38% at Liaoyang, 45.50%at Tianjin), indicating that CB-7 and CB-8 catalysts have exceeded R-32 catalyst and reached E-803 catalyst in activity and selectivity for BTX production. CB-7 catalyst has been in continuous operation for 708 days without regeneration while the depentanized reformate yield and aromactics yield are not significantly reduced at the end of run,indicating that its stability has exceeded that of E-803 catalyst.
