Abstract

A dependence of the selectivity and reaction rate in the preparation of aromatic hydrocarbons from methane on ZSM zeolites in the present of some nitrous oxide on the chemical composition and structure of zeolite catalysts has been examined. The activity is shown to increase with increasing the concentration of decationated sites of the ZSM zeolites. The low activity of the Y zeolite is likely to be due to a fast poisoning of its acid centers by coke formation.

Abstract

Исследована зависимость селективности и скорости реакции синтеза высших углеводородов из метана на цеолитах типа ZSM с применением закиси азота от химического состава и структуры цеолитных катализаторов. Показано, что активность цеолитов типа ZSM возрастает с увеличением в них концентрации декатионированных мест. Низкая активность цеолита типа Y, возможно, связана с быстрым отравлением его кислотных центров продуктами уплотнения.
