摘要：

The dealkylation and realkylation of ethylbenzene over silica-deposited MFI zeolite have been studied. The relationship between para selectivity enhancement and extent of silica deposition is established. The effects of reaction conditions like variation in reaction temperature and weight hourly space velocity on the high para selectivity feature of modified zeolite are examined. A study of the kinetics of the reaction in the temperature range 523-573 K is carried out. The estimated activation energy is similar to that reported for toluene disproportionation over MFI zeolite.
