Description

technical field [0001] The invention relates to the technical field of coal gasification, in particular to a hydrogen-rich reaction system coupled with coal gasification and a carbon removal method for coal gasification. Background technique [0002] China's thermal power installed capacity has reached 1.14 billion kilowatts, and my country's current energy structure is still dominated by coal, accounting for 58% of energy consumption. Among them, compared with the traditional coal-fired power generation technology, the performance of the overall coal gasification technology is higher, which is conducive to further reducing carbon emissions. [0003] Coal gasification refers to the process in which coal, coke, semi-coke and other solid fuels react with gasification agents under high temperature, normal pressure or pressurized conditions, and are converted into gas products and a small amount of residue. The gasification agent is mainly water vapor, air or their mixed gas. T...
