The present invention relates to a gas-phase process for the preparation of butadiene comprising

Process for the preparation of butadiene

Described is a process for the production of a zeolitic material having an MFI, MEL, and/or MWW-type framework structure comprising YOand XO. The process comprises (1) preparing a mixture comprising one or more sources for YO, one or more sources for XO, and one or more solvents; (2) crystallizing the mixture obtained in step (1) to obtain a zeolitic material having an MFI, MEL and/or MWW-type framework structure; and (3) impregnating the zeolitic material obtained in step (2) with one or more elements selected from the group of alkaline earth metals. Y is a tetravalent element, and X is a trivalent element. The mixture crystallized in step (2) contains 3 wt.-% or less of one or more elements M based on 100 wt-% of YO, wherein M stands for sodium.

Production and use of a zeolitic material in a process for the conversion of oxygenates to olefins

The present invention relates to a catalyst for the conversion of oxygenates to olefins, wherein the catalyst comprises one or more zeolites of the MFI, MEL and/or MWW structure type and particles of one or more metal oxides, the one or more zeolites of the MFI, MEL and/or MWW structure type comprising one or more alkaline earth metals, and the particles of the one or more metal oxides comprising phosphorus, the phosphorus being present at least partly in oxidic form, and the one or more alkaline earth metals being selected from the group consisting of Mg, Ca, Sr, Ba and combinations of two or more thereof, to the preparation and use thereof, and to a process for converting oxygenates to olefins using the catalyst.
