摘要：
Active sites for C2H4 hydrogenation produced by reduction of V2O5/Al2O3 catalyst pretreated at 450-degrees-C were found to be composed of both strong Lewis acid sites associated with V4+ and basic sites of Al2O3. C2H4 polymerization concurrent with hydrogenation was assumed to occur on Lewis acid sites with higher acid strengths than those of the hydrogenation sites.
