NOVELTY - The process involves hydrogasifying a carbon-containing resource using hydrogen at a temperature and pressure sufficient to form a reaction effluent composed of methane, hydrogen and carbon dioxide. The reaction effluent is cleaned to remove gases other than methane, hydrogen and carbon dioxide and particulates. The cooled reaction effluent is processed through a water shift reactor.    USE - Used for producing methane from a carbon-containing resource such as carbon, peat, biomass, oil, tar sand and any hydrocarbon, in coal mining industry, natural gas production industry, and energy production industry.    ADVANTAGE - The process improves mining process of the methane, and dramatically expands potential for the economic recovery of coal-derived fuel. The process is safe and friendly one, and avoids the pollution associated with combusting coal products, and creates substitute natural gas from coal beds and above-ground energy resources.    DETAILED DESCRIPTION - The cooled reaction effluent is processed through a water shift reactor to convert the carbon monoxide to hydrogen to a gaseous outflow of hydrogen, methane, and carbon dioxide. The outflow of hydrogen, methane, and carbon dioxide is separated into separate streams and carbon dioxide stream is produced as a product gas. A first portion of the methane stream in a steam reformer, water gas shift reactor and gas separator is processed to produce segregated flows of hydrogen and carbon dioxide. The segregated hydrogen flow is combined with the separated hydrogen stream. The combined hydrogen stream is heated and repressurized to the temperature and pressure of the hydrogen in the first step and second portion of the methane stream is produced as a product gas, wherein the second portion is the amount of methane not subjected to processing in the steam reformer, water gas shift reactor and gas separator. The heated and repressurized hydrogen in the hydrogasifing step is used to continue the process.    DESCRIPTION OF DRAWING(S) - The drawing shows a process for producing methane from an underground coal seam.
