【摘要】 为了寻求清洁能源,充分利用煤炭资源,采用煤炭地下气化技术,通过应用膜分离法及PSA相结合方法来提高煤炭地下气化煤气中氢气质量分数。对于浓度低的,先用膜分离使其“提浓”,再进行PSA吸附,使其“提纯”,会得到高纯度氢气.,同时其成本远远低于其他提氢方法。结果表明,煤炭地下气化方式制氢气是化石燃料制氢气的有效途径之一.更多还原

【Abstract】 With the aim of making a search for clean source of power,make the best use of the coal resources,we adopt the underground coal gasification technology.The hydrogen concentration of the UCG coal gas is increased by the barrier separation and PSA combine,and the high content of hydrogen is obtained by improving purity,and at the same time its cost is by far lower than other hydrogen methods.The result indicate the production of hydrogen by the UCG is one of the efficiency approach in the hydrogen making by use of fossil fuel.更多还原
