説明
For the removal of acid gases discharged from municipal solid waste incineration, simultaneous / individual sorption of HCl and / or SO2 by using Na2CO3 was investigated in the temperature range of 473-1073K. The tested gas mixture in N2 balance was set to the respective concentrations as follows: 1000ppm HCl, 200ppm SO2, 5% O2 for simultaneous sorption; 1000ppm HCl for individual HCl sorption; 200ppm SO2, 5% O2 for individual SO2 sorption. The sorption capacity as well as sorption rate for HCl / SO2 sorption of Na2CO3 fine particle (dp <5 μ m) was evaluated by the gas inlet-outlet measured by material balance.<BR>As a result, the total capacity of simultaneous sorption of HCl and SO2 was lower than that of individual sorption of HCl or SO2, in the temperature range of 473-673K. On the other hand, the total capacity of HCl and SO2 for simultaneous sorption of HCl and SO2 was increased with temperatures of the range of 873-1073K. The sum of HCl and SO2 sorption amount was about 1.4 times larger than that of individual sorption of HCl or SO2 at 1073K. SEM / EDS analysis revealed that the amount of Cl distributed on the surface of the particle was about 20 times larger than that of S heated at 673K. This result indicated that sodium chloride formed on the surface of particles prevented SO2 to react with Na2CO3.<BR>An effective diffusion coefficient of HCl for chlorination of Na2CO3 was in the magnitude 10-11, which was about twice higher than that of SO2 under simultaneous sorption of HCl and SO2.
