Analysis of the Factors in Affecting the Performance of Coal Liquefaction

Coal liquefaction is a conversion processes which coal generates liquid hydrocarbon and little gas hydrocarbon by its catalytic hydrogenation. Nitrogen, oxygen, sulfur and other heteroatoms were removed from coal at the same time. Coal liquefaction is not only conducive to improve the utilization of coal resources, but also would ease China's oil tense situation. Improve the conversion efficiency of coal is the focus of coal liquefaction research, and the influence factor on coal liquefaction rate were discussed in this paper. It mainly related to coal type, coal petrographic macerals and catalysts.
