Research progress of metal sulfide adsorbent for mercury removal from flue gas

综述了金属硫化物吸附剂的主要类型及其脱汞性能、负载的选取及其特点、金属硫化物的改性方法及其有利效果,以及其它以金属硫化物作为脱汞有效组分的新型吸附剂,并选取了具有代表性的吸附剂进行了整理,提出了制备多元金属硫化物吸附剂、研制适应不同烟气组分的吸附剂以及开发金属硫化物吸附剂再生和汞回收工艺等研究方向和建议,为进一步研发有效的气相脱汞材料并应用于工程实践提供了参考。

The main types of metal sulfide adsorbents and their mercury removal performance,the selection and characteristics of the load,the modification methods of metal sulfides and their favorable effects,as well as other new adsorbents with metal sulfides as effective components for mercury removal were reviewed.The representative adsorbents were selected and sorted out.The research directions and suggestions for the preparation of multi-metal sulfide adsorbents,the development of adsorbents suitable for different flue gas components,and the development of metal sulfide adsorbent regeneration and mercury recovery processes were proposed,which provided a reference for the further development of effective gas-phase mercury removal materials and their application in engineering practice.
