我国煤基活性炭生产技术现状及发展趋势 -

活性炭在环保领域得到日益广泛的应用,尤其是水处理用煤基活性炭已成为活性炭的主流产品。综述性评价了煤基活性炭主要生产技术及设备的现状,总结了煤基活性炭孔结构调控的方法,分析了煤基活性炭产业的发展趋势。结果表明,压块活性炭生产技术的推广和多膛炉的应用使得煤基活性炭生产规模大型化成为现实,通过配煤、添加剂和优化炭化、活化工艺参数可以制备出多样化和专用化的煤基活性炭。 Activated carbon has been widely used in the field of environmental protection,especially the coal-based activated carbon used in water treatment has become the main product of activated carbons.A critical review on status of technology and equipment for coal-based activated carbon production was presented. In addition,the approaches to regulating pore structure of coal-based activated carbon were summarized.Finally,the development trend of coal-based activated carbon industry was briefly analyzed.The results show that with the popularization of the preparation technology of activated carbon by briquetting method and application of multiple hearth furnace,production of coal-based activated carbon on large scale becomes a reality and it is possible to prepare diversified and specialized coal-based activated carbon by coal blending,introducing additives in raw coal and optimizing carbonization and activation process parameters
