Abstract

Active sites for C2H4 hydrogenation produced by reduction of V2O5/Al2O3 catalyst pretreated at 450°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.

Abstract

Активные центры гидрогенизации C2H4, образующиеся при восстановлении катализатора V2O5/Al2O3, предварительно обработанного при 450°C, содержат как сильно кислые льюисовские центры, так и основные центры Al2O3. Полагали, что на центрах льюисовской кислоты с силой, превышающей необходимую для гидрогенизации, конкурентно протекает полимеризация C2H4.
