摘要： The present invention relates to a process for preparing a molding comprising a zeolitic material and one or more oxidic binders, the process particularly comprising preparing a mixture of a zeolitic material, such as Mg-ZSM-5, a source of an oxidic binder, and a first plasticizer; admixing an acid to said mixture; and shaping of the mixture, to obtain a precursor of a molding; wherein in said mixture a specific weight ratio of the source of the oxidic binder to the sum of the zeolitic material and the source of the oxidic binder is applied. Further, the present invention relates to a molding obtainable or obtained by the inventive process, and to a molding itself displaying in particular a comparatively improved crush strength. Yet further, the present invention relates to a method for the conversion of oxygenates to olefins and to a use of the inventive molding.
