The present invention relates to a catalyst for the conversion of oxygenates to olefins, the catalyst containing one or more zeolites of an MFI-, MEL- and/or MWW-type structure and particles of one or more metal oxides, wherein the one or more zeolites of the MFI-, MEL- and/or MWW-type structure contain one or more alkaline earth metals, and the particles of the one or more metal oxides contain phosphorus, the phosphorus being at least partially present as an oxide, 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 of these elements. The invention also relates to the production and use of said catalyst and to a method for the conversion of oxygenates to olefins using the catalyst. |
