Abstract
A catalyst of vanadium oxide supported on cerium oxide and zirconium oxide is specified. The catalyst comprises 0.1-10 wt % vanadium oxide relative to the total catalyst weight, and the catalyst is in the form of microparticles. A method using a wetness impregnation technique to produce the catalyst is described. The use of the catalyst in the oxidative dehydration of methanol to produce dimethyl ether is specified, along with the catalyst's stability for reaction periods of 50 or more hours.
