Abstract: |
The liquefaction of lignite is a technology by chemical processing methods makes the group of coal into liquid products, including direct liquefaction and indirect liquefaction. In this paper, experiments on brown coal liquefaction method, extraction of raw materials of high value-added. and we also discussed the impact of raw materials, solvents, catalysts and temperature﹑pressure and time on coal liquefaction. Production of liquid fuel from the lignite is to efficient and clean use of coal, increasing the liquid fuel source, developing the coal chemical industry, and also is an important way to reduce coal pollution solutions, put forward the direction of comprehensive utilization of lignite.
