Abstract
Process for treating a zeolite catalyst for the carbonylation of dimethyl ether to produce methyl acetate, in which the catalyst is contacted with a treatment gas containing water vapor in an amount of at least 1 mol % and at a temperature below which dealumination of the zeolite structure occurs. The zeolite contains at least one channel which is defined by an 8-member ring and is mordenite.
