摘要
采用低负载量的 ( 0～ 3% ) Ag/γ- Al2 O3 体系作为 C3 H6选择性催化还原 ( C3 H6- SCR)NO的催化剂 ,考察了银负载量、反应温度、空速对 NO转化率的影响 .同时对于原料气中氧的作用进行了研究 .结果表明 :银负载量为 1 .5 %时 ,催化剂表现出最高的反应活性 ;在考察的条件范围内 ,原料气中含氧对 NO的还原有促进作用 ,适宜的氧浓度为 0 .2 7% ;反应温度的过高会导致还原气中 C3 H6大幅度转化为
The selective catalytic reduction of NO with propene in the presence of O 2 are carried out over low silver loading Ag/Al 2O 3 catalyst (0 3 %). The effects of silver loading, O 2 content and GHSV on NO conversion are studied. The results show that O 2 can promote the reduction of NO and the highest NO conversion are achieved while silver loading is 1.5 % and O 2 content is 0.27%. More C 3H 6 are converted into CO 2 with the reaction temperature increasing.
