  • Publication number: 20230095488
    Abstract: The present invention relates to a process for preparing a molding comprising a mixed oxide comprising O, Mg, and Ni, the process comprising: —(i) mixing water, a Mg source, a Ni source, and an acid, to obtain a mixture; —(ii) subjecting the mixture obtained from (i) to a shaping process; —(iii) calcining the molding obtained from (ii) in a gas atmosphere having a temperature in the range of from 700 to 1400° C.; wherein the molar ratio of the acid used in (i) to Ni, calculated as elemental Ni, of the Ni source used in (i), acid:Ni, is equal to or higher than 0.001:1. Further, the present invention relates to a molding comprising a mixed oxide comprising O, Mg, and Ni, wherein the mixed oxide comprises a specific crystalline phase NixMgyO, wherein the sum of x and y is 1, and wherein y is greater than 0.52. The molding is used for reforming methane to a synthesis gas comprising hydrogen and carbon monoxide.
