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: The present invention relates to a process for carrying out a chemical reaction in a chemical reactor, in which at least one starting material, which is an organic chemical compound comprising 1 to 80 carbon atoms, is converted into at least one reaction product in a fluid phase in the presence of a film comprising solid catalyst particles, which catalyze said chemical reaction, and comprising an organic polymer in fibrillated form, wherein the mass fraction of the sum of the starting material and of the reaction product based on the total mass of the fluid phase is in the range from 0.01 to 1.
