Abstract: The invention relates to a method for activating a catalyst for catalytic reforming that is particularly carried out with carbon dioxide being reacted, and according to which an activation gas that contains steam and hydrogen is passed over the catalyst to be activated at an activation temperature during an activation period. The activation gas comprises 10 to 30 mol-% steam, 40 to 60 mol-% hydrogen and 20 to 40 mol-% one or more inert gases.

Abstract: The present invention relates to a supported copper catalyst comprising Cu, Zn, Al, Zr, Si, and O, wherein the catalyst comprises elemental copper, and wherein the catalyst displays a Zn:Si atomic ratio in the range of from 5:1 to 27:1, as well as to a precursor of the catalyst. Furthermore, the invention relates to a process for the preparation of a catalyst and catalyst precursor, respectively, as well as to a method for the conversion of CO2-containing syngas to methanol, and to a method for the conversion of syngas to dimethyl ether which respectively employ the inventive catalyst.

Abstract: A process for synthesis of dimethyl ether is proposed, in which a feed gas mixture (E) containing carbon dioxide and/or carbon monoxide and hydrogen is guided through reaction tubes (1) of a cooled shell and tube reactor (10) that are equipped with a first catalyst and a second catalyst, in which the carbon dioxide present in the feed gas mixture (E) and/or the carbon monoxide present in the feed gas mixture is at least partly reacted over the first catalyst with the hydrogen present in the feed gas mixture to give methanol, and in which, in the same shell and tube reactor (10), the methanol is at least partly converted over the second catalyst to dimethyl ether. It is envisaged that the reaction tubes (1) are equipped with the first and second catalysts in the form of a structured bed, where the structured bed has two to four regions (11, 12, 13) in which the first and second catalysts are provided in different physical mixtures, where the regions (11, 12, 13) are arranged such that the concentration of the first catalyst increases in a flow direction through the reaction tubes (1). Also proposed is a plant (100) for implementation of such a process.
