摘要：Rice husk gasification char (RHGC) was the in- dustrial solid waste of biomass gasification power plant, which had a good adsorption effect on mercury in flue gas. Its mercury adsorption performance was improved after modification of halogen elements. This paper used adsorption kinetics method to ana- lyze adsorption mechanism of modified RHGC. The results showed that the quasi-second-order kinetic model had the highest fitting degree and R2 could reache above 0.992; mercury was mainly adsorbed by the active sites on the adsorbent surface and chemical adsorption was dominant, which will pro- vide theoretical reference for the efficient utilization of RHGC.
