Abstract
Рассмотрено использование модифицированных форм цеолитсодержащих пород (ЦСП), содержащих смесь цеолитов, в качестве катализаторов процесса дегидратации метанола до диметилового эфира. Изложены результаты исследования влияния химического модифицирования на активность и стабильность катализаторов. Показана принципиальная возможность использования модифицированных пород, содержащих морденит и клиноптилолит, в качестве катализаторов процесса превращения метанола. Определен вклад каждой цеолитной составляющей в характеристики катализатора.
The use of modified forms of zeolite-containing rocks (ZCRs) that comprise a mixture of zeolites as catalysts for the dehydration of methanol to dimethyl ether has been studied. Results of examination of the effect of chemical modification on the activity and stability of the catalysts have been described. It has been shown that modified rocks containing mordenite and clinoptilolite can be in principle used as methanol conversion catalysts. The contribution of each of the zeolite components to the catalyst performance has been determined.
