Abstract
A process of producing a catalyst based on pentasil-type crystalline aluminosilicate is described, including the steps of (a) treating hydrous aluminum oxide with an aqueous, acid-containing medium, (b) mixing the hydrous aluminum oxide treated with aqueous, acid-containing medium from step (a) with an H-zeolite and (c) calcining the mixture obtained in step (b). In addition, a catalyst is disclosed which is obtained by such a process, as well as its use in CMO and OTO processes.
