Abstract

Coke deposited on heterogeneous catalysts can be characterized by temperature programmed oxidation. The comparison between the amount of CO2 produced and the amount of O2 consumed gives the ratio H/C. For Pt/Al2O3 catalysts it has been shown that coke deposited on the metal is less dehydrogenated than coke deposited on the support.

Abstract

Отложение кокса на гетерогенных катализаторах характеризуют температурно-программированным окислением. Сравнением количества образующегося CO2 с количеством израсходаванного O2 получают отношение H/C. Показано, что в случае катализатора Pt/Al2O3 углерод на металле менее дегидрировах, чем углерод на носителе.
