| 中文摘要: |
| 烧结烟气中的SO2是形成酸雨的主要来源。目前常用的湿法脱硫、干法脱硫和半干法脱硫,治理成本高且存在二次污染。通过制备负载型铁系催化剂Fe2O3/γ-Al2O3,在SO2＋CO＋N2氛围下进行催化还原脱硫;在400℃时10%Fe2 O3/γ-Al2 O3催化剂其脱硫率达84%。 |
| 英文摘要: |
| Primary acid rain source is Sulfur dioxide in sintering gas,At present,the desulphurization ways are wet method,dry method and half-dry method,but cost of the methods is expensive and secondary pollution.The method of directly catalyzing CO to reduce SO2 into substance of S,has the advantages of avoiding the emergence of secondary pollution.In the paper,we prepared a series of iron catalysts.With the SO2+CO+N2 system,the desulfurization rate is 84% by 10% Fe2O3/γ-Al2O3 at 400 ℃. |
