Abstract: 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.

Abstract: The present invention relates to a specific process for the preparation of a zeolitic material, wherein the framework structure of the zeolitic material comprises Si, O, and a tetravalent ele-ment M other than Si, wherein M is selected from the group consisting of Ti, Sn, Zr, Ge, and mixtures of two or more thereof. Further, the present invention relates to a zeolitic material obtainable or obtained by said process, the zeolitic material itself and its use. In addition thereto, the present invention relates to a molding comprising said zeolitic material.

Abstract: The present invention relates to a catalyst for hydrogen peroxide activation, wherein the catalyst comprises Ti, Si, and O, wherein the catalyst displays a water adsorption (W), a concentration (C) of bridging μ2 η2-peroxo species per Ti in the H2O2-activated catalyst as determined by quantitative 17O NMR spectroscopy, and a specific activation factor (A) according to formula I, wherein in accordance with formula I, the activation factor is the multiplication product of the water adsorption and the concentration of bridging μ2 η2-peroxo species per Ti in the H2O2-activated catalyst: A=W×C (I). The present invention further relates to a method for the preparation of a catalyst molding as well as to a catalyst molding comprising a catalyst for hydrogen peroxide activation obtainable or obtained by said process. Yet further, the present invention relates to a process for the activation of hydrogen peroxide, and to the use of the inventive catalyst or of the inventive catalyst molding in a reaction involving C—C bond formation and/or conversion.
