Abstract

Hydrogenation of benzene, toluene, o,m and p-xylene over Pt, Pd and Pt−Pd/Al2O3 catalysts has been studied. Experimental data show that when Pd is added to Pt catalysts, a decrease in activity and changes in selectivity occur. This is explained by the formation of electron-deficient and electrorich metallic species.

Abstract

Было исследовано гидрирование бензола, толуола, о-, м- и п-ксилолов на катализаторах Pt, Pd и Pt−Pd/Al2O3. На основе экспериментальных данных было установлено, что при добавлении Pd к катализатору Pt происходит уменьшение активности и изменение селективности. Это объясняется образованием электронообедненных и электрониообогащенных металлических частиц.
