车用燃料发展趋势对煤液化的影响 (二)煤液化中碳氢氧三元素的合理利用

The Influence of the Vehicle Fuel Development to the Coal Liquefaction (2)The Efficient Usage of the Carbon ,Hydrogen and Oxygen in the Coal Liquefaction

本文根据机动车燃料清洁化和绿色化的趋势 ,从工艺技术的成熟性、经济性、投资、最终产品使用性能、燃料和能源结构以及国家能源安全等多个方面比较了煤直接液化和间接液化生产液态烃燃料工艺和煤生产CH3 OH和CH3 OCH3 车用燃料技术 ,表明煤生产CH3 OH和CH3 OCH3 车用燃料可以合理有效利用煤中的碳氢氧 ,符合车用燃料的发展趋势 ,并提出了合理利用煤中碳氢氧三元素的煤综合分级利用的新工艺设想 ,以最为经济。

In this paper, according to the trend of the vehicle fuel cleaning and greenness, coal directly liquefaction and indirectly liquefaction to produce the oil and the technology of the coal to produce the CH 3OH and CH 3OCH 3 are contrasted from the maturity and economical of the technology, investment, the using character of the final product, the energy structure and the state energy safety. It shows that the production of CH 3OH and CH 3OCH 3 from coal can use the carbon ,hydrogen and oxygen of coal efficiently, accord with the trend of the vehicle fuel. The new technology of coal integrate and grade usage is put forward, which can make use of the coal the most economical and cleaning.
