Catalyst is prepared by precipitating Ni and Al hydroxides from a solution of their nitrates containing 4 times as much Ni nitrate as Al nitrate, the washed precipitate is formed into a shaped mass and dried, all these operations being conducted at a temperature < 30°, and the Ni hydroxide is subsequently reduced at a temperature of about 250°. Example: A mixture of CO and coal gas is treated for removal of S. The resulting gas consisting mainly of CO, H₂, and CH₄ in proportion of 1:2:1, still containing about 45 mg. S per 1. is passed over the catalyst at about 350°. The resulting gas contains over 50% CH₄.
