Abstract：The development of new catalytic materials that could be applied in the industrial production of aromatics was reviewed in this paper, including composite molecular sieve, nano-sized zeolites with large channels, core-shell molecular sieve and ZSM-12, etc. BEA/MOR co-crystallized molecular sieve, mesoporous mordenite, nano-sized zeolite, and MFI/BEA or MOR/BEA core-shell molecular sieve had good performance for conversion of heavy aromatics. MFI/MFI core-shell zeolite, especially the SRZ-1 with b-oriented silicalite-1 shell, exhibited good shape-selective performance in the methylation of toluene with methanol. Based on nano-sized ZSM-5 with high ratio of Si to Al, MTX-1000 toluene methylation catalyst was successfully applied in the 200 000 tons per year MTX industrial demonstration unit at Yangzi petrochemical company and exhibited excellent catalytic performance.
