説明
For the purpose of effective HCl gas removal from municipal solid waste incineration, a comparison was made for CaO and Na2CO3 sorbent for HCl sorption, in terms of HCl sorption capacity as well as HCl sorption rate. HCl gas sorption tests of CaO and Na2CO3 were conducted by using a flowtype tube reactor packed with fine particles under the particle diameters of 5 μm in the temperature range of 473-1073 K, at a total flow rate of 3×10-4 m3·min-1, of which the inlet gas mixture were HCl (1000 ppm) -N2. As the results, a maximum conversion value of 0.92 for HCl removal by CaO was obtained at 873 K. On the other hand a maximum conversion value of 0.87 was obtained for Na2 CO3 at 673 K. The rates of HCl sorption by CaO and Na2CO3 were explained by chemical reaction rate control under the present conditions. The pore of CaO was confirmed to disappear by sintering above the temperature of 973 K, which led to the reduction of HCl sorption capacity. A maximum HCl sorption capacity of Na2CO3 was obtained at 673 K, in which the crystal structure of Na2CO3 started to transform to Natrite. The reduction of HCl sorption capacity was attributable to the reduction of pore volume caused by the change in crystal structure.
