In range of 300℃~900℃, all the transition metal oxide catalysts could get high ammonia conversion, during the initial stages of the reaction, the SO〓 conversion is relatively low since the catalysts have not been sulfureted, but it increases gradually and attain constant with rising temperature and time continuance,〓 is better than other catalysts in reactivity and elemental sulfur selectivity; XRD indicates that, in the SO〓-SCR process, stable transition metal sulfide is generated which is very important to SO〓 reduction and transition metal sulfide probably is the active phase of catalyst, further the reduction of SO〓 by H〓 to H〓S is the limiting step of all process, then the activity is somewhat related to its lattice oxygen yet not so notable; XPS indicates that little sulfur on surface exists as S〓 in sulfate, showing that TiO〓 could restrain the generation of sulfate.

对于过渡金属氧化物催化剂的研究发现,在300℃~900℃范围内,不同的催化剂均可获得很高的NH〓转化率,反应初期由于催化剂还未硫化,所以SO〓的转化率较低,随着温度升高和反应时间的延续,SO〓的转化率逐渐升高并达到了稳定值;七种过渡金属氧化物中,以〓对于NH〓还原SO〓反应的活性和选择性最好;XRD结果表明在NH〓-SO〓反应后生成了稳定的硫化物相,硫化物对SO〓的还原过程具有重要作用,催化剂的活性相可能是过渡金属硫化物,而且在硫化物催化剂上进行的H〓还原SO〓生成H〓S的反应是整个过程的速率控制步骤,所以催化剂的活性与其自身的晶格氧的氧化还原能力有一定的联系,但关系不明显;XPS结果表明催化剂表面的硫大部分以过渡金属硫化物的形式存在,只生成少量的S〓,说明TiO〓催化剂能够较好的抑制硫酸盐的生成。
