J. Das et al., REACTIONS OF ETHYLBENZENE IN THE PRESENCE OF TOLUENE OVER EXTERNAL SURFACE PASSIVATED MFI ZEOLITE, Catalysis letters, 20(3-4), 1993, pp. 349-357
The reactions of ethylbenzene in the presence of toluene were studied
over external surface passivated MFI zeolite. With increase in extent
of external surface passivation the para selectivity of both transalky
lation and disproportionation reactions enhanced. The effects of mole
ratio of ethylbenzene to toluene, reaction temperature and WHSV on the
performance of the modified zeolite are discussed. It was observed th
at the high para selectivity feature of the modified zeolite is not in
fluenced by changes in reaction conditions.
