METHANATION OF CARBON MONOXIDE WITH EFFECTIVE HEAT REMOVAL

摘要

METHANATION OF CARBON MONOXIDE 12816 WITH EFFECTIVE HEAT REMOVAL Carbon monoxide-containing gas streams are converted to methane by a cyclic, essentially two-step process in which said carbon monoxide is disproportionated to form carbon dioxide and active surface carbon deposited on the surface of a catalyst, and said carbon is reacted with steam to form product methane and by-product carbon dioxide. The exothermic heat of reaction generated in each step is effectively removed during each complete cycle so as to avoid a build up of heat from cycle-to-cycle, with particularly advantageous techniques being employed for fixed bed, tubular and fluidized bed reactor operations.
