The reactivities of hydrated limes for gaseous HCl removal were investigated at temperature region of 200~300℃ and compared with that of calcium hydroxide slaked by deionized water. Experimental data show that slaked limes hydrated by NaOH and Na2CO3 solutions are most reactive, which implies that the slaked limes have been modified by sodium alkali, i.e. NaOH and Na2CO3.

Dilute aqueous solutions of NaOH, Na2CO3 and NaCl were used to hydrate CaO. The reactivities of hydrated limes for gaseous HCl removal were investigated at temperature region of 200~300℃ and compared with that of calcium hydroxide slaked by deionized water. Experimental data show that slaked limes hydrated by NaOH and Na2CO3 solutions are most reactive, which implies that the slaked limes have been modified by sodium alkali, i.e. NaOH and Na2CO3. Primary researches using ASAP2000 microporemeter and SEM pictures show that three features of the slaked limes contribute to their enhanced reactivities when hydrated by sodium alkali solutions: (1) raised BET area and porosity, (2) modified pore size distribution, i.e. increased porosity in the diameter region of 50~200A, which is favorable for the removal reaction, (3)the product layers are more porous.

用很稀的NaOH、Na2CO3、NaCl溶液代替纯水消化生石灰,测试并比较生成的Ca(OH)2与不含这些物质的Ca(OH)2在中低温段(200~300℃)净化酸性气体HCl的反应能力.试验表明用钠碱NaOH和Na2CO3溶液消化生成的Ca(OH)2较用纯水和NaCl溶液消化生成的Ca(OH)2具有更高的反应能力,即钠碱对Ca(OH)2具有改良作用.初步研究表明,含有钠碱的氢氧化钙反应能力较高的主要原因有:(1)孔容积和比表面积提高;(2)孔隙率分布改善,最佳孔径区(50~200A)内的BJH孔隙率和比表面积递增密度增大;(3)反应产物层疏松多孔,减少了扩散阻力.
