چکیده:

The conversion of methanol to dimethyl ether was carried out over commercial H-ZSM-5 and γ-Al2O3 catalysts to evaluate their catalytic performances. The activity of each catalyst was examined in the dehydration of crude methanol to DME using a fixed-bed microreactor at a reaction pressure of 2barg and LHSV of 15 h_1. The catalysts characterized by XRD technique. The results showed that the H-ZSM-5 exhibited better activity in dehydration of methanol
