Abstract

Abstract: The loading, drying, start-up of C₈aromatics isomerization catalysts,RIC-200 and RIC-270 ,in two proprietary aromatics complex units in SINOPEC Hainan Refining& Chemical Co. were introduced, and the performance of the two catalysts were compared. The results showed that compared with RIC-200 catalyst, RIC-270 catalyst was better in isomerization activity and ethylbenzene conversion rate, which could make the unit produce more p-xylene.

Key words: aromatics complex unit, isomerization, catalyst, para-xylene
