中文摘要：
在SCRDeNOx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SCRDeNOx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-Fe2O3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-Fe2O3作原始催化剂外加γ-Fe2O3脱硝有一定的现实意义．
英文摘要：
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.
