| 摘 要： | 随着国内能源消费的增长，特别是车用燃料的迅速增长，石油消费总量越来越大，但国内石油资源有限，专家预计2010年和2020年石油的对外依存度将达到50%和60%，威胁国家能源的安全供应.但我国煤炭资源相对丰富，大力发展以煤为原料的合成液体替代燃料，提供部分车用燃料，将是解决能源安全供应问题的重要途径之一.论述和比较了合成煤基燃料的3种不同工艺路线：煤直接液化合成油，煤间接液化合成油和煤基含氧燃料合成.前两种工艺的主要目标是提高燃料的H/C比，以合成粗油或碳氢化合物为目标产物.新一代煤直接液化合成油技术还没有工业化装置投入运行，但间接F-T合成碳氢燃料已有成功的工业经验.和石油基燃料相比，虽然煤基碳氢燃料还不具有明显的经济优势，但对于石油资源有限的中国具有重要的战略意义.煤间接液化也可合成煤基含氧燃料，即甲醇燃料和二甲醚燃料等.和碳氢燃料相比，合成煤基含氧燃料不仅具有明显的技术和经济优势，而且充分利用了煤中C、H和O 3种主要元素，可以实现资源、能源、环境和经济可持续发展.

| Abstract: | With rapidly growing demand for energy,especially for transportation fuels,China is likely to turn to coal as a basis for providing synthetic liquid fuels for transportation and other applications.Three alternative approaches to providing liquid fuels from coal:direct coal liquefaction,indirect coal liquefaction and synthesis of coal-based oxygenated fuels,are described and compared in this paper.In the first two cases a major challenge is to increase the ratio of hydrogen to carbon and the objective product is synthetic crude oil or hydrocarbon fuel.Modern technology of direct coal liquefaction has not yet been commercialized,while Fisher-Tropsch synthesis is well established commercially.Even though coal-based hydrocarbon fuels do not have significant economic advantages as compared with petroleum products,they have significant strategic importance in energy security in China.Two oxygenated fuels from coal, methanol(MeOH) and dimethyl ether (DME), can also be derived via indirect liquefaction.The oxygenated fuels from coal has a unique advantage in both technology and economy, which is derived from economical utilization of C,H,and O in coal. |
