Abstract
The side-chain alkylation of toluene with methanol has been studied over a number of prospective zeolite catalysts, such as Na-X, Cs-X and Cs-B-X at atmospheric pressure in a fixed-bed reactor. Cs-X zeolite showed a higher activity than Cs-B-X and Na-X zeolites with respect to toluene conversion and yield of styrene. The effects of reaction temperature and molecular ratios of reactants have been investigated. The maximum toluene conversion of 25.5% and styrene to ethylbenzene mole ratio of 4 : 1 are obtained with Cs-X zeolite. The catalysts show good stability as found with time-on-stream studies.
