Abstract: The effects of reaction temperature, flow rate of carrier gas, space velocity andbenzene to propene ratio on the alkylation of benzene with propene over Hβ zeolitewere investigated.At lower flow rate of carrier gas and space velocity, higher ben-zene to propene ratio the formation of cumene is favoured due to the difference be-tween rates of reactions of the alkylation of benzene (or cumene) with propene andthe alkyltranslation of diisopropylbenzene with benzene.The propylbenzene is pro-duced directly by the alkylation of benzene with propene.

Key words: Benzene, Propene, Alkylation, H&beta, zeolite
