摘要
介绍了煤气化粗渣(CGCS)的特性,重点分析了CGCS循环再利用技术的研究与发展现状.目前,CGCS主要应用在建筑材料和功能材料两个方面.在建筑材料方面,CGCS可以作为制备轻质骨料、胶结材料、墙体材料、免烧砖、地质聚合物等的原料;在功能材料方面,CGCS可以用来合成多孔材料及改性复合材料,经过酸浸等方法处理,还可以提取贵金属.最后指出了未来CGCS资源化利用的发展趋势.
Abstract
The characteristics of coal gasification crude slag(CGCS)were introduced,focusing on the research and development status of CGCS recycle and reuse technology.At present,CGCS was mainly applied to two aspects:construction materials and functional materials.In terms of construction materials,CGCS could be used as raw materials for the preparation of lightweight aggregates,cementitious materials,wall materials,baking-free bricks,geopolymers,etc.In terms of functional materials,CGCS could be used to synthesize porous materials and modified composite materials,and after acid leaching and other treatments,it could be used to extract precious metals.Finally,the future development trend of CGCS resource utilization was pointed out.
