The invention relates to the mining industry and can be used at geotechnological control of coal beds at theirs underground gasification. A method for production of hydrogen from the coal bed, comprising drilling of injection and bleeding wells with pipe columns in the coal bed, connecting of wells along the bed by hydraulic fracturing, bed sparking around the packer of injection well, sequential air supply for heating of the bed to the temperature of 1250 °C and heat water supply in the heated bed through the injection well with production of synthesis-gas, sequential removing of combustion products and synthesis-gas, formed in the bed, through the bleeding well, where the set thermodynamic conditions are maintained. At the stage of heating of coal bed the pipe column in bleeding well is filled from the surface with waste sorbent, from which the carbon monoxide is preliminary removed, in which at the stage of production of synthesis-gas for sorption of carbon monoxide the temperature of 65-70 °C and pressure of 1.3-1.4 MPa are maintained with subsequent upstop of waste sorbent and production of hydrogen, at that the regeneration of the waste sorbent is realized by the combustion products. The use of the invention allows to increase the process efficiency and to produce the commercially pure hydrogen from the contaminated coal beds. |
