我国能源资源禀赋和煤气化产业的发展使煤气化渣排放量已达6000万t/a。大量的煤气化渣堆存不符合能源清洁低碳高效利用的理念。对煤气化渣进行消纳处理过程中,由于含水量高、含碳量高,限制了规模化利用途径,因此需转换传统思路,向高值化方向进行性能开发是一种趋势。重点综述了煤气化渣在高值化方面的研究进展,概述了煤气化渣的来源及物理化学性质,总结了国内外煤气化渣在催化剂框架、聚合物补强、多孔材料、农业堆肥等高值化方面的研究现状,提出了高值化利用存在的局限性问题,展望了未来的发展方向。煤气化渣高值化利用是固废性能开发的主要形式,可降低生产成本,减少环境污染,并且煤气化渣的特性显示煤气化渣是错位的资源,适度开发其在高值化方面的应用,可实现煤气化渣变废为宝。

China′s energy resource endowment and the development of coal gasification industry have made the emission of coal gasificationslag up to 60 million t/ a. A large amount of coal gasification slag is not in line with the concept of clean, low-carbon and efficient use ofenergy. In the process of coal gasification slag absorption treatment, due to the high water content and carbon content, the way of largescale utilization is limited, so it is a trend to change the traditional idea and develop the performance in the direction of high value. Research progress of high-value gasification slag was focused on, the sources and physical and chemical properties of coal gasification slagand the research status at home and abroad in the high-value gasification of catalyst framework was summarized, polymer reinforcement,porous materials, agricultural compost and other aspects. The limitations of high-value utilization was put forward, and the future development direction was looked forward. High-value utilization of coal gasification slag is the main form of solid waste performance development, which can reduce production costs and environmental pollution. Moreover, the characteristics of coal gasification slag showthat coal gasification slag is a misplaced resource, and moderate development of its application in high-value utilization can realize thetransformation of waste into treasure.
