Abstract

Alkylation of benzene with ethane was carried out using various zeolite catalysts at temperature ranges of 400-550 degreesC. Loading of platinum ontozeolite greatly enhanced the yield of ethylbenzene. Among the zeolites tested, H-ZSM5 and H-MCM22 showed catalytic activities. By contrast, mordenitedid not yield ethylbenzene. Moderate acid strength distribution is the keyfactor of zeolite catalysts. Optimum catalyst and conditions for this reaction are as follows. The platinum-loaded H-ZSM5 catalyst containing 6.8 wt%Pt, at a reaction temperature of 500 degreesC, afforded ethylbenzene and styrene formation rates of 14.2 and 0.8 mmol h(-1) g-cat(-1), respectively (benzene-based yields 7.3 and 0.4%). In the alkylation of benzene with ethane over platinum-loaded H-ZSM5. ethene was initially formed from ethane overthe metallic platinum. Then the alkylation proceeded over the acid sites of H-ZSM5.
