淮南气煤直接液化特性的研究

笔者从淮南矿区具有方便的交通、适中的地理位置、充足的电力和丰富的水源以及宜人的气候等综合条件考虑 ,结合矿区丰富的气煤资源和良好的液化特性 ,并根据气煤的元素组成 (碳、氢、氧 )和发热量 (Qgr,dmmf及Qnet,ar)比长焰煤和褐煤更接近于天然石油的事实 ,可以认为淮南气煤适于直接液化且综合经济效益将明显优于低煤化度的不粘、长焰煤和褐煤 The huainan coal-mining district possesses a good transport service, a well-situated, abundant power and water supply, pleasant weather. The gas coal resource is abundant and its direct liquefaction character is also good in Huainan coal mining district. Its C, H, and O elemental content and Qgr,dmmf and Qnet,ar heating value are more and more closed with the natural petroleum comparison with the long flame and brown coal Therefore it may consider that the comprehensive economic benefit of Huainan gas coal direct liquefaction will be better than the low degree of coalification coal such as non-coking coal, long flame coal and brown coal
