| 摘 要： | 采用碳酸钾(K_2CO_3)与活化半焦通过浸渍法制备用于除去烟气SO_2的催化脱硫材料(K/ASC)。研究表明,将活化半焦(ASC)通过10%(质量分数)K_2CO_3改性获得钾基半焦(K10),其在120℃时具有良好的SO_2脱除效率,而且随着再生温度的升高(400～700℃),再生后K10的脱硫活性明显提高。K10(K10-R-600-n)的循环再生测试表明,样品在4次再生循环(K10-R-600-4)后具有最佳的脱硫性能,其硫容量为68.9 mg·g-1,比K10(55.4 mg·g-1)高24.37%。再生分析脱硫产物为物理吸附的SO_2,H_2SO_4和硫酸盐,再生后未分解的硫酸盐沉积会降低样品的脱硫活性。经过10次循环再生(K10-R-600-10),样品的硫容量为初始钾基半焦K10的70%。
