摘要
随着煤间接液化技术的日益成熟,副产物气化炉渣的产生亦逐渐增多。气化炉渣作为固体废弃物的一种,其处理处置问题已是当前煤间接液化行业的热点问题,然而对气化炉渣的综合利用研究更是急需考虑的发展方向。介绍了我国煤间接液化技术的背景,发展现状及未来趋势,论述了煤间接液化的工艺流程、气化炉渣的产生、危害及组成。同时概括了国内外气化炉渣在污水处理和建筑行业上的研究现状,论述了气化炉渣在铺路、制备免烧砖、生产混凝土和制备矿渣硅酸盐水泥等方面的应用。最后,提出了气化炉渣在利用局限性、产品缺陷性方面存在的问题,同时为其在污水处理中的应用提出了新思路。
In order to improve utilization rate of gasification slag,the background,research status,future trends of indirect coal liquefaction technologies in China were introduced,and the process of indirect coal liquefaction,generation,hams and composition of gasification slag were reviewed. The domestic and foreign research status of gasification slag in waste water treatment and construction industry were summarized. The gasification slag was mainly used in paving,preparation of baking- free bricks,concrete and Portland cement and other aspects. The problems of gasification slag existing in limitations of application and defects of products were discussed.
