Abstract

The promotion of a K/Fe/silicalite-2 catalyst with lanthanum increases the selectivity of C2–C4 olefin and conversion of carbon monoxide. The influence of lanthanum on the catalyst has been characterized by TPR, TPD and XPS techniques. The suitable lanthanum content in the chemical composition of the catalyst is determined.

Abstract

Промотирование катализатора K/Fe/силикалит-2 лантаном повышает селективность олефинов C2–C4 и конверсию моноокиси углерода. Влияние лантана на катализатор изучали с помощью ТПВ, ТПД и РФЭС методов. Определяли оптимальное содержание лантана в катализаторе.
