| Abstract: | The influence of the impregnation concentration of copper nitrate in a porous alumina pellet on the SO2 adsorption efficiency has been investigated. The mechanism of adsorption and pore clogging has been analysed on the basis of the partitioned pore structure model and the results has been compared with the experimental breakthrough curves. The complete conversion of the pellet was attained in the low concentration of impregnation. The breakthrough time could be increased by increasing the concentration in the range from 2.0 to 6.0 mol// copper nitrate solution when the SO2 concentration was about 3000 ppm. The conversion rate however, dropped rapidly as the pore clogging occurred at the higher concentration than the optimum level. |
