Abstract

Nonoxidative conversion of methane to aromatic hydrocarbons on granulated Мо/ZSM-5 catalysts was studied. The catalysts prepared using zeolites with the hierarchic pore system surpass in activity the catalysts prepared by the traditional method, mixing of powdered Н-ZSM-5 with pseudoboehmite, followed by granulation and calcination. The textural characteristics of the granulated zeolites and of Mo-containing catalysts based on them were studied. The catalyst samples contain micro-, meso-, and macropores, but the pore formation pattern in the granulated catalysts with the hierarchic pore system and in the catalysts containing 30% binder is different.

Mo / ZSM-5颗粒催化剂上的非氧化甲烷转化

摘要

研究了颗粒状Мо/ ZSM-5催化剂上甲烷的非氧化转化为芳烃。使用具有分层孔系统的沸石制备的催化剂在活性上优于通过传统方法制备的催化剂，将粉末状的Н-ZSM-5与假勃姆石混合，然后进行制粒和煅烧。研究了粒状沸石和基于它们的含钼催化剂的结构特征。催化剂样品包含微孔，中孔和大孔，但是具有分层孔系统的粒状催化剂和包含30％粘结剂的催化剂中的孔形成模式不同。
