چکیده:

Clinoptilolite, a natural zeolite, has been investigated as the basic raw material to synthesize a catalyst for
methanol dehydration to dimethyl ether and a novel kinetic model, based on Langmiure-Hinshelwood
method, was presented for the reaction with the optimized catalyst and the kinetic parameters were
determined as functions of temperature. The modified clinoptilolite zeolite subject of this study might be of
high industrial interest because of the relative lower activation energy (ca. 60 kJ mol-1 ) compared to other
reported zeolitic and nonzeolitic catalysts.
