Abstract 1. A SINGLE STAGE PROCESS FOR PRODUCING METHANE SUBSTANTIALLY DEVOIDE OF ANY CARBON OXIDE FROM A GASEOUS MIXTURE OF HYDROGEN AND AT LEAST ONE CARBON OXIDE WHICH COMPRISES: (A) HEATING SAID GASEOUS MIXTURE TO A TEMPERATURE WITHIN THE RANGE OF 200 TO 450*C., AND (B) PASSING SAID GASEOUS MIXTURE AT A FLOW RATE OF FROM 10 TO 500 VG VC-1 HR.-1 AND UNDER A PRESSURE OF AS LOW AS ONE ATMOSPHERE IN CONTACT WITH A CATALYST COMPOSITION CONSISTING ESSENTIALLY OF A TRANSITION METAL CATALYST INTERCALATED WITHIN THE CRYSTALS OF A CRYSTALLIZED CARBON GRAPHITE, THE CARBON ATOMS HAVING A DEFINITE PLANAR ALIGNMENT AND WHEREIN THE TRANSITION METAL IS IN THE METALLIC STATE HAVING A ZERO VALENCE, AND IS SELECTED FROM THE GROUP CONSISTING OF NICKEL, PALLADIUM AND PLATINUM, THEREBY TO PRODUCE METHANE GAS SUBSTANTIALLY DEVOID OF ANY CARBON OXIDE.
A SINGLE STAGE PROCESS FOR PRODUCING METHANE SUBSTANTIALLY DEVOIDE OF ANY CARBON OXIDE FROM A GASEOUS MIXTURE OF HYDROGEN AND AT LEAST ONE CARBON OXIDE WHICH COMPRISES: (A) HEATING SAID GASEOUS MIXTURE TO A TEMPERATURE WITHIN THE RANGE OF 200 TO 450*C., AND (B) PASSING SAID GASEOUS MIXTURE AT A FLOW RATE OF FROM 10 TO 500 VG VC-1 HR.-1 AND UNDER A PRESSURE OF AS LOW AS ONE ATMOSPHERE IN CONTACT WITH A CATALYST COMPOSITION CONSISTING ESSENTIALLY OF A TRANSITION METAL CATALYST INTERCALATED WITHIN THE CRYSTALS OF A CRYSTALLIZED CARBON GRAPHITE, THE CARBON ATOMS HAVING A DEFINITE PLANAR ALIGNMENT AND WHEREIN THE TRANSITION METAL IS IN THE METALLIC STATE HAVING A ZERO VALENCE, AND IS SELECTED FROM THE GROUP CONSISTING OF NICKEL, PALLADIUM AND PLATINUM,
