ADVANCES ON THE RESEARCH AND DEVELOPMENT OF CATALYSTS FOR TOLUENE DISPROPORTIONATION AND C_9 AROMATICS TRANSALKYLATION

摘要

Advances on the development of commercial catalysts using in the processes such as Tatoray(Toluene Disproportionation and C_9 Aromatics Transalkylation of UOP Company), MTDP (Toluene Disproportionation Process of Mobil Company), S-TDT (Toluene Disproportionation and C_9 Aromatics Transalkylation of SRIPT), Trans-Plus, PX-Plus (Selective Toluene Disproportionation of UOP Company) and MSTDP (Selective Toluene Disproportionation Process on Mobil's ZSM-5 catalyst) have been Reviewed. The trends on the research of the new catalysts such as ZSM-5, Beta, MCM-22, Omega, SAPO and modified Y for the selective toluene Disproportionation process and for the toluene disproportionation and C_9 Aromatics transalklation have been described.
