以煤气化为核心的多联产系统仍然是解决我国能源领域可持续发展的重要途径之一，因此产生的气化炉渣排放量也逐年递增，气化炉渣作为固体废弃物之一，若不及时有效处理，必将严重破坏生态环境，因此气化炉渣的综合利用成为研究的热点之一。而气化炉渣比表面积大、孔隙发达是制备多孔吸附材料的理想原料。介绍了煤气化炉渣的来源、性质与应用，多孔材料的制备方法，论述了煤气化炉渣基多孔吸附材料在CO2的捕集、水中酚类的吸附、染料废水的净化和生物质焦油处理方面的应用，从而为化工企业废弃物的有效处理提供思路。

 A coal gasification-based multi-product system remains one of the important solutions to sustainable energy development in China, and as a result, the amount of slag generated from gasification has been increasing year by year. Slag, as one of the solid waste, will seriously damage the ecological environment if not properly and effectively treated. Therefore, the comprehensive utilization of slag has become a hot research topic.However, the large specific surface area and porous structure of the gasified slag make it an ideal raw material for preparing porous adsorbent materials. The sources, properties, and applications of coal gasification slag, the preparation methods of porous materials were introduced, and the applications of porous materials based on coal gasification slag in capturing CO2, removing phenols from water, treating dye-contaminat-
ed wastewater, and treating biomass tar were discussed. It was provided that a new perspective for the effective treatment of industrial waste in chemical enterprises.
