Abstract: The present invention relates to a specific process for the reforming of ammonia, wherein the process comprises (i) providing a reactor containing a catalyst comprising a metal M1 selected from the group consisting of Ni, Co, or Ni and Co; (ii) preparing a feed gas stream comprising NH3; (iii) feeding the feed gas stream prepared in (ii) into the reactor provided in (i) and contacting the feed gas stream with the catalyst, wherein contacting is performed at a pressure of 1 to 50 bara, and at a temperature of 400 to 1,100° C.; (iv) removing an effluent gas stream from the reactor, the effluent gas stream comprising H2 and N2.

Abstract: The present invention relates to an adiabatic, zoned reactor for the reforming of NH3 to N2 and H2, the reactor particularly comprising n reaction zones arranged in sequence and extending along the axial length L of the reactor, wherein n is an integer in the range of from 2 to 5, wherein independently from one another, each of the n reaction zones comprises one or more catalytic components, wherein from the inlet reaction zone to the outlet reaction zone each reaction zone displays a lower light-off temperature T50 in the reforming of NH3 to N2 and H2 then the subsequent downstream one. Further, the present invention relates to a production unit comprising said reactor, a process for the reforming of NH3 to N2 and H2, and use of said reactor and said production unit.

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.
