摘要
废弃SCR脱硝催化剂是能源行业产生的典型难处理多金属危险废物,国内年排放量可达50万m3,因此,废弃SCR脱硝催化剂的高效处置,以及对废弃SCR脱硝催化剂中有价元素进行资源化回收利用颇为必要.介绍了废弃SCR脱硝催化剂的性质,综述了废弃SCR脱硝催化剂处置方式和资源化回收的研究进展,对比了各类回收技术的优缺点,展望了废弃SCR脱硝催化剂的高效回收利用.
Abstract
Waste denitration catalyst is a typical refractory muti-metal hazardous waste from the energy industry,and its annual emission reaches 500,000 m3 in China.Therefore,the efficient disposal of waste SCR denitrification catalysts and the recycling of valuable elements in waste SCR denitrification catalysts have become the focus of current research.In this review,we introduced the properties of waste SCR denitrification catalysts,summarized the research progress of disposal methods and resource recovery of waste SCR denitrification catalysts in recent years,and compared the advantages and disadvantages of each method.Finally,the efficient recovery and utilization of waste SCR denitrification catalysts were prospected.
