摘　　要：分析了褐煤液化理论及影响因素,结合湿法气化技术,提出褐煤部分液化、液化残渣气化的分级转化技术,探索褐煤综合化、洁净化、集成化的利用途径。分析表明,褐煤具有较高的加氢液化活性,通过气化与液化技术结合,能够实现褐煤的高效利用。To explore a comprehensive, clean and integrated utilization of lignite, the theory of lignite liquefaction and influencing factors are analyzed, and the staged conversion technology of lignite that part of lignite is liquefied and the residual char is gasified combining with the wet gasification is pro- posed. The result shows that the lignite is very active in hydrogenation liquefaction. By combining the technology of gasification and liquefaction ,lignite can be utilized efficiently.
