Water gas is passed over hot reduced Ni. The composition of the water gas is maintained constant by employing a constant temperature in the furnace, and the gas is subjected, after passing through a solution of Na₂CO₃, to a 2d decarbonator in a NaOH or KOH lye. Having sufficient moisture after this treatment, the gas is passed over the Ni without addition of H₂O vapor.
