摘要:The aim of this paper is to study SO2 adsorption by the activated carbon ( AC) in the circulating fluidized bed reactor. Five different kinds of activated carbons were chosen to determine whether activated carbon could be used effectively to remove SO2 from coal combustion flue gas. The fluidized bed reactor was used to study the capability of AC in SO2 removal with concentrations of SO2 ( 1000ppm), O-2 ( 20%) and H2O ( 3-8%) and react temperature ( 40-72.). The pore structure, pore size distribution and functional groups of five activated carbons were analyzed and characterized in this paper. The results showed that SO2 adsorption capability of CAC and MAC was larger than others. In general, there was no correlation between SO2 adsorption capacity and surface area. Basic functional group was benefit for SO2 adsorption. React temperature, C/S mole ratio, oxygen and water concentration has greater effect upon the SO2 removal. The optimum conditions for desulphurization by CFB reactor were H2O ( 8%) outlet temperature ( 60-65 degrees c), and C/S mole ratio ( 80). In fluidized state, the absorption capacity of activated carbons varied from 45-81mg/g, and the average adsorption rate was 25.5 to 40mg/(g . s).
