N2 - The conversion of heavy reformate to xylenes over H-mordenite-based catalysts was studied with different concentrations of acid sites in a fluidized bed reactor. The effects of a mixture of mordenite and ZSM-5 catalysts on C9 conversion, selectivity to xylenes, and product distribution were investigated. The composition of heavy reformate can significantly alter the reaction rates and product yields over mordenite-based catalysts. The yield of total xylenes increased significantly by mixing mordenite with ZSM-5 zeolite. Mixing ZSM-5 and mordenite showed appreciable advantage, while mixing lower-acidity M2 with higher-acidity Z1 resulted in the highest xylenes yield. The conversion of toluene and heavy reformate over lower-acidity M2Z1 increased xylenes yield to a maximum of 25.3 wt % from a feed mixture containing 70:30 heavy reformate and toluene. This is an abstract of a paper presented at the 20th Annual Saudi-Japan Symposium on Catalysts in Petroleum Refining and Petrochemicals (Dharan, Saudi Arabia 12/5-6/2010).
