氢能是当今人类理想的清洁能源。在煤炭地下气化过程中 ,制氢原理包括H2 O (气态 )的分解、热解作用及CO的变换反应。实验室模型实验、煤炭地下气化半工业性试验及工业性试验结果表明 ,采用长通道、大断面、双火源、两阶段煤炭地下气化新工艺 ,可实现所生产的地下水煤气中H2 含量基本均在 50 %以上 ,最高可达 72 3 6%。 Hydrogen energy is the ideal clean energy of mankind today. In the underground coal gasification process, the principle of hydrogen production includes decomposition of H 2 O (gas), pyrolysis and CO shift reaction. Laboratory model experiments, semi-industrial tests of coal underground gasification and industrial test results show that the use of long channels, large cross-section, double fire source, two-stage underground coal gasification process can be achieved in the production of groundwater gas H2 content Basically more than 50%, up to 72 3 6%.
