Selective production of xylenes from alkyl-aromatics and heavy reformates over dual-zeolite catalyst
Original language description
Disproportionation of 1,2,4-trimethylbenzene (1,2,4-TMB), its transalkylation with toluene as well as dealkylation of ethyltoluenes (ETs) over MOR and MFI zeolites were investigated in a fluidized-bed reactor at 300?400 °C. MFI exhibited good ET conversion (60 wt.%), high dealkylation selectivity (60%), but low disproportionation and transalkylation activities. MOR showed high ET conversion (80 wt.%) with low dealkylation selectivity (33%), and high disproportionation and transalkylation activities. Based on these results, a dual-zeolite catalyst consisting of MOR and MFI was proposed to promote the diverse reactions leading to selective production of xylenes via dealkylation?transalkylation of alkylaromatics. Single-zeolite (MOR-based) and dual-zeolite (MOR- and MFI-based) catalysts were prepared by addition of binder, characterized and evaluated for the conversion of C8+ and C9+ heavy reformates (either alone or with the addition of various amounts of toluene).
