摘要
SO_2是大气的主要污染物之一,将SO_2还原为单质硫,既能消除SO_2对大气的污染,又能回收硫.综述了以C,H_2,CH_4,CO和NH_3为还原剂,用催化还原法将SO_2转化为硫的研究进展,讨论了各种催化还原脱硫方法的特点及应用前景.
SO_2 is one of the most serious air pollutants. Reducing SO_2 into S not only removes air pollution but also recycles. This article shows the research development on how reactions reduce SO_2 into S by way of catalyzing reduction with C, H_2, CH_4, CO, NH_3 as reducers and discusses the characteristics of catalyzing reduction as well as application prospect.
