| 中文摘要: |
| ４种国产活性炭被用于ＮＯ还原反应，其中，山楂核炭和山桃核炭具有较高的ＮＯ还原转化率。实验发现，表面含氧基团－ＣＯＯ－对活性炭自身的还原性和对ＮＯ的还原活性有很重要的影响。对表面富－ＣＯＯ－基团的活性炭，稀盐酸处理使表面－ＣＯＯ－显著分解。 |
| 英文摘要: |
| Pour different active carbons were used both as the support for CuO and as the reducing agent by itself for NO reduction.The active carbons from hawthorn nut and mountain peach nut gave higher conversions.It was demonstrated that the surface oxide-COO-on the active carbon had a great influence on its reducing ability and NO reduction conversion.However,the surface oxide-COO-decomposed when it was treated by hydrochloric acid.In contrast,the treatment by concentrated nitric acid increased the amounts of-COO-and all oxygen-containing groups.Thereby,the higher conversion of NO reduction can be obtained at relatively low temperatures. |
