The natural gas, used in the parent patent for producing metallic nickel powder, is mixed, relative to its proportions of saturated hydrocarbons, preferably methane, with gaseous carbon dioxide. At 400-500 degrees C over a nickel catalyst, the gas mixture is largely converted to carbon monoxide and hydrogen according to the general equation CnH2n+2 + n CO2 -> 2n CO + n+1 H2 The gas enriched with CO and H2 is then more suitable for the reduction of the NiOx according to the process of the parent patent than the unreformed natural gas itself. The reaction can also take place directly on the NiOx.
