ABSTRACT A highly reactive carbonaceous material is disclosed which comprises at least 0.5 weight percent of a ferrous group metal component bonded to the carbon in the material. Also disclosed are processes for manufacture of this carbonaceous material and processes for using it to manufacture methane. The carbonaceous material may be in two forms, unpromoted carbonaceous material and hydrogen promoted carbonaceous material. The unpromoted material is formed by contacting a carbon monoxide- containing gas with a ferrous group metal carbon monoxide disproportionation initiator under conditions where the required amount of ferrous group metals diffuse into and bond at least partly to free carbon depositing on the bulk ferrous group metal initiator. The hydrogenated promoted material is formed by contacting the unpromoted material with hydrogen. The source of the carbon monoxide may be a producer gas derived from burning coal. our material includes the free carbon as a continuous major phase and one or more ferrous group metals, metal alloys, or metal carbides associated with and bonded to the free carbon as dispersed minor phases.
