【Abstract】 Effects of hydrogen sulfide on alkylation of benzene with ethylene over catalyst FX-02 were studied. It implied that sulfide hydrogen sulfide had occupied the active sites of the catalyst and impeded the adsorption and reaction of reactants. Thus the desulfuration of FCC off-gas is necessary in the process of ethylbenzene synthesis using FCC off-gas as feedstock over catalyst FX-02.更多还原
