Stability of Zeolite HZSM-5 in Liquid Phase Dehydration of Methanol to Dimethyl Ether

Stability of Zeolite HZSM-5 in Liquid Phase Dehydration of Methanol to Dimethyl Ether

A high performance HZSM-5 catalyst for liquid phase dehydration of methanol to dimethyl ether (DME) was developed by optimizing Si/Al ratio and hydrothermal treatment temperature. During 6788 h long term test, DME selectivity kept above 99.96% and only slight deactivation was observed primarily due...

Zusammenfassung:A high performance HZSM-5 catalyst for liquid phase dehydration of methanol to dimethyl ether (DME) was developed by optimizing Si/Al ratio and hydrothermal treatment temperature. During 6788 h long term test, DME selectivity kept above 99.96% and only slight deactivation was observed primarily due to coking and decline of HZSM-5 crystallinity. Graphic Abstract
