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.

• 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。
