摘要
我国西部地区中新生代赋存着丰富的低煤级(Rmax<0.8%)煤炭资源,且绝大部分为低灰、低硫、低磷的优质煤,这为煤的洁净利用提供了最佳的液化原料。从煤质和煤岩基本性质出发,探讨了研究区低煤级煤的液化性能。通过高压釜在溶剂和催化剂条件下的加氢液化试验可知,在氢耗量5%左右时,煤的液化转化率达90%以上,油产率达55%以上,这表明我国西部低煤级煤可作为重要的液化用煤资源。同时,通过分析影响本区煤液化性能的控制因素,发现煤的挥发分产率、碳氢原子比、活性组分含量和镜质体反射率等指标可直接影响煤的液化性能。
In the west region of China, Mesozoic and Cenozoic low rank coal resources are abundant. The coal seams are of low ash, low sulfur, low phosphorous and excellent quality, constituting the best material for liquefaction from the view of clean utilization. Based on the characteristics of coal quality and coal petrology, the liquefac- tion property of low rank coal in the studied areas is discussed in the paper. In the condition of solvent and catalyzer by Autoclave, the Hydro-liquefaction experimentation indicates that the hydrogen consumption is 5 %, conversion rate is about 90 %, the rate of liquid of coal is about 55 %, showing that low rank coal of the west China is important liquefaction resources. According to analysis of factors controlling coal liquefaction behavior, it was found that the volatile yields, atom ratio of hydrogen and carbon, active component content and vitrinite reflectivity affect directly liquefaction behavior.
