摘　　要：在SCR DeNOX试验中,研究了在各种催化剂作用下,加入γ-Fe2O3细颗粒对NOX脱除的促进作用.结果表明,γ-Fe2O3对SCR DeNOX有一定的促进作用,但对不同的原始催化剂其促进效果不一.用γ-Al2O3做原始催化剂外加γ-Fe2O3的促进作用最为明显,最大脱除效率从39.6%提升到55.2%,且最佳反应温度降低了30℃.用γ-Al2O3作原始催化剂外加γ-Fe2O3脱硝有一定的现实意义.The promoting effect of γ-Fe2O3 on removing NOx from flue gas was studied while using different original catalysts in the experiment of SCR DeNOx. The results indicate that the promoting effects of γ-Fe2O3 vary with the SCR catalysts. While γ-Fe2O3 as the original catalyst and γ-Fe2O3 as the additional catalyst, the promoting effect of γ-Fe2O3 is the most visible and the maximal DeNOx efficiency rises from 39. 6% to 55.2% , and also the optimum reaction temperature reduces by 30℃. Using γ-Fe2O3 as the original catalyst and γ-Fe2O3 as the additional catalyst for DeNOx is feasible to practice.
