摘　　要：煤炭在中国能源消费结构中长期占有重要位置,这与煤炭储量多、分布较广密不可分。然而煤炭利用技术仍不完善,碳转化率不高,导致温室气体大量排放,能源有效利用率平均约33%。氢能作为一种绿色清洁能源,以热值高、零污染排放为特点,将是未来能源发展的焦点。对以煤炭为原料制氢的技术手段进行经济优势评价,结合中国能源结构、分布特征、能源有效利用率等横向对比分析电解水制氢技术、甲醇制氢技术、煤制氢技术、天然气制氢技术以及其他制氢技术等成本优势。结果表明,以煤炭为原料制氢成本可降低空间大,对煤炭利用而言能源有效转化率高。Coal plays an important role in China's energy consumption structure for a long time,which is closely related to the characteristics of large coal reserves and wide distribution.However,the technology of coal utilization is still not perfect,the low carbon conversion rate leads to large greenhouse gas emissions,and the average effective energy utilization rate is about 33%.As a kind of green and clean energy,hydrogen energy,characterized by high calorific value and zero pollution emission,will be the focus of energy development in the future.In this paper,the technical means of hydrogen production with coal as raw material will be evaluated for economic advantages,and the cost advantages of electrolytic water hydrogen production technology,methanol hydrogen production technology,coal hydrogen production technology,natural gas hydrogen production technology and other hydrogen production technologies was compared and analyzed based on the energy structure,distribution characteristics and effective utilization rate of energy in China.The results show that the cost of hydrogen production from coal can be reduced greatly,and the energy conversion rate is high for the utilization of coal.
