Study on the removal of Hg 0 from flue gas by coal dry powder gasification coarse slag

         

摘要

The prevention and treatment of mercury in coal-fired power plants has always been the focus and difficulty. How to control the pollution of mercury to human body and ecological environment quickly and effectively is a hot research topic nowadays. As a low cost and potential adsorbent,there is a huge space for the development of coal dry powder gasification coarse slag. In this paper,Mercury osmotic tubes are heated by water bath tank as mercury source,and the scavenging effect of adsorbent on Mercury monomer under different influence conditions is explored. The adsorbent plays an important role in adsorption of mercury monomer because of its special active sites on the surface. The reason is that the adsorbent surface is rich in carboxyl group,hydroxyl functional group,combined with mercury to form complexes. This shows that chemical adsorption facilitates the adsorption process.
