| titleOfInvention | Biological-high temperature gasification combined mining method for hydrogen production from coal |
| abstract | The invention discloses a biological-high temperature gasification combined mining method for hydrogen production from coal, which comprises the following steps: drilling two horizontal well groups on the same horizontal plane in a coal seam, and setting a casing for well cementation; hydraulic fracturing is carried out on the two wells simultaneously to form a boundary fracture gap network; performing alkali treatment on a coal seam, injecting coal-based hydrogen-producing microbial liquid into the coal seam in two horizontal wells, enabling strains to diffuse along critical fractures, dynamically monitoring the temperature and pressure conditions of the strains to prevent the strains from being inactivated, promoting microorganisms to strip coal carbon hydrogen-containing functional groups and capture metabolism by using the temperature and pressure conditions of the coal seam, performing multi-stage degradation on organic components in coal to generate hydrogen, carbon dioxide and micromolecular acid, and realizing in-situ carbon-hydrogen separation of the coal and preparing the hydrogen; discharging and extracting hydrogen after the bottom hole pressure reaches a peak value and is kept stable; and (3) gasifying and producing hydrogen for the remaining coal bed through the reaction of supercritical water and high-temperature carbon, and pumping gas and then injecting slurry to fill the combustion space area. The invention realizes low-carbon, green and high-efficiency development of coal by subverting the traditional coal mining technical system through biological-high-temperature gasification multistage utilization. |
