我国拥有丰富的煤炭资源，但石油资源相对贫乏，对外依赖度高，因此发挥我国煤炭能源优势，大力发展煤直接液化技术就成为改善我国能源结构的重要选项之一。煤液化残渣是煤炭直接液化后的主要副产品，约占液化原料的20% ~ 30%，是一种极具利用价值的重质碳资源。当前，煤液化残渣的利用方式有气化、热解、焦化、碳材料和沥青改性剂等，但由于组成复杂，从而限制了其所含组分的高效利用，因此本文对如何合理高效利用煤液化残渣组分的当下研究热点展开论述。

China is rich in coal resources, but oil resources are relatively poor and highly dependent on foreign countries. Therefore, giving full play to China 's coal energy advantages and vigorously developing coal direct liquefaction technology has become one of the important options to improve China 's energy structure. Coal liquefaction residue is the main by-product of direct coal liquefaction, accounting for about 20% ~ 30% of the liquefied raw materials. It is a heavy carbon resource with great utilization value. At present, the utilization methods of coal liquefaction residue include gasification, pyrolysis, coking, carbon materials and asphalt modifier. However, due to complex composition, the efficient utilization of its components is limited. Therefore, this paper discusses the current research hotspot that how to rationally and efficiently utilize the components of coal liquefaction residue.
