Effect of Reaction Conditions on the Catalytic Dehydration of Methanol to Dimethyl Ether Over a K-modified HZSM-5 Catalyst

Effect of Reaction Conditions on the Catalytic Dehydration of Methanol to Dimethyl Ether Over a K-modified HZSM-5 Catalyst

The effect of temperature, pressure, space velocity and feed-stream water content in the synthesis of dimethyl ether from methanol over a K-HZSM-5 catalyst was evaluated with respect to the activity, physicochemical properties and deactivation of the catalyst. Increasing the water content in the fee...

Zusammenfassung:The effect of temperature, pressure, space velocity and feed-stream water content in the synthesis of dimethyl ether from methanol over a K-HZSM-5 catalyst was evaluated with respect to the activity, physicochemical properties and deactivation of the catalyst. Increasing the water content in the feed stream allowed to proceed the reaction over a wider temperature range. Despite a decrease in the methanol conversion at low temperatures (
