Abstract:
Method for producing olefins through reaction of carbon monoxide with hydrogen in the presence of an iron-containing heterogeneous catalyst, characterized in that the catalyst used comprises carbonyl iron powder with spherical primary particles.
Abstract:
The present invention relates to a catalyst for the conversion of oxygenates to olefins, comprising a carrier substrate and a layer applied to the substrate, the layer containing one or more zeolites of an MFI-, MEL- and/or MWW-type structure, wherein the one or more zeolites contain one or more alkaline earth metals. 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.
Abstract:
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.
Abstract:
The present invention relates to a method for the conversion of oxygenates to olefins, comprising the steps of (1) providing a gas stream that contains one or more ethers; and (2) contacting the gas stream provided in (1) with a catalyst; the catalyst comprising a carrier substrate and a layer applied to the substrate, wherein the layer contains one or more zeolites of an MFI-, MEL- and/or MWW-type structure.
