%X 在煤炭直接液化生产过程中,会产生占液化原煤质量30%左右的液化残渣。它是一种高碳、高灰和高硫的物质,主要由未转化的煤、液化中间产物、无机矿物质以及煤液化催化剂组成。煤炭直接液化残渣有很高的利用价值,无论从经济角度还是环保角度出发,都需要对残渣进行利用,这也是煤炭直接液化工业化必须解决的问题。综述了煤炭直接液化残渣的来源、组成、性质、加氢研究现状及应用等。 Direct coal liquefaction(DCL)produces a lot of residue.The quantity of direct coal liquefaction residue (DCLR)is about 30%(mass fraction)based on the amount of coal.DCLR is a mixture with high carbon,high ash and high sulfur contents,which comprises unconverted coal,intermediate products,inorganic mineral matter and residual catalyst.DCLR has high utilization value as well as economic and environmental benefits.The source,composition, properties,current situation about hydrogenation research and application of DCLR are summarized
