摘要
综述了近年来国内外对废弃钒钛系脱硝催化剂中有价金属资源化回收的研究进展,主要包括浸出和分离两个阶段的研究。重点分析了浸出工艺中酸浸、碱浸和焙烧回收浸出的原理、工艺和研究进展,并结合国内外研究和传统方法的处理过程、工艺特点、环境影响和经济效益等方面进行对比分析,总结其研究重点方向为酸碱浸出辅以化学沉淀法的结合,可实现催化剂中有价金属的工业化回收,为该领域未来研究发展提供技术性参考。
The research progress of valuable metals from SCR denitration catalyst formed in recent years were reviewed,mainly inciuding undergo and separation stages.The paper analyse the principles,processes,research progresses of different leaching solution by acid/alkali/sodium roasting process.Combined with the domestic and foreign research status,the traditional and new methods of treatment process,process characteristics,environmental impact and economic benefits are introduced nd compared.A mong them,the acid/base leaching combined with chemical precipitation can relize the industrial recovery of valuable metals in the catalyst,with a view to providing a technical reference for future research and development in this field.
