Research progress of metal sulfide adsorbent for mercury removal from flue gas
The main types of metal sulfide adsorbents and their mercury removal performance,the selec-tion 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 re-viewed.The representative adsorbents were selected and sorted out.The research directions and sugges-tions for the preparation of multi-metal sulfide adsorbents,the development of adsorbents suitable for dif-ferent flue gas components,and the development of metal sulfide adsorbent regeneration and mercury re-covery processes were proposed,which provided a reference for the further development of effective gas-phase mercury removal materials and their application in engineering practice.
