our kinds of active carbon (AC), which were made from coconut shell (CS), hawthorn nut (HN), mountain peach nut (PN) and coal (C) respec tively, were used in the reduction of NO as both support and reducing agent. It was found that the conversion of NO was different on different kinds of active carbon, i. e. CuO/HNAC and CuO/PNAC gave comparatively higher conversion of NO; however, the conversion was lower over CuO/CSAC andCuO/CAC.

our kinds of active carbon (AC), which were made from coconut shell (CS), hawthorn nut (HN), mountain peach nut (PN) and coal (C) respec tively, were used in the reduction of NO as both support and reducing agent. It was found that the conversion of NO was different on different kinds of active carbon, i. e. CuO/HNAC and CuO/PNAC gave comparatively higher conversion of NO; however, the conversion was lower over CuO/CSAC andCuO/CAC. This great disparity was well concerned with their elemental composition? NH3-TPD results, reducing ability and amount of adsorbed NO. In addition, the dispersion of Cu(Ⅱ) on active carbons had also a greatinfluence on NO reduction. It was demonstrated that the higher NO conversion below 400℃ on Cuo/HNAC was due to its better dispersion of Cu(Ⅱ)than CuO/ PNAC. In contrast, the reducing ability of the supports became aleading factor of C and NO reaction over CuO/HNAC and CuO/PNAC above 400℃ Therefore, it was concluded that NO(a)→N (a) +O(a) is a ratelimiting step below 400℃, however, C+2O (a)→CO2 become rate-limiting foroverall reaction C+ 2NO→CO2+N2 at above 400℃.

四种国产活性炭既作为载体又作为还原剂被用于NO还原反应.山楂核炭和山桃核炭作载体时NO还原转化率很高,椰壳炭和煤质炭作载体时NO还原转化率则较低.四种活性炭两-两分组现象可由其元素分析、NH3-TPD、还原性及NO吸附量等结果来解释.另外CuO/椰壳炭与CuO/煤质炭的NO还原转化率的差别主要归因于二者的NO吸附量不同.对CuO/山楂核炭和CuO/山桃核炭,NO还原转化率随反应温度的相对变化主要由其还原性和Cu(Ⅱ)的分散度决定.由此推断出在400℃以下时,NO(a)→N(a)+O(a)是速控步骤,400℃以上时,C+2O(a)→CO2是速控步骤.

Molecular oxygen led to a sudden increase in the conversion of NO reduction over the four active carbons (AC) supported cupric oxide. The four active carbons were CSAC, HNAC, PNAC and CAC made from coconut shell, hawthorn nut, mountain peach nut and coal, respectively. The leap of NO conversion resulted from the fast and large formation of surface oxides, especially carboxyls and lactones, on the active carbons due to the partial oxidation by O 2 at a definite temperature.

Molecular oxygen led to a sudden increase in the conversion of NO reduction over the four active carbons (AC) supported cupric oxide. The four active carbons were CSAC, HNAC, PNAC and CAC made from coconut shell, hawthorn nut, mountain peach nut and coal, respectively. The leap of NO conversion resulted from the fast and large formation of surface oxides, especially carboxyls and lactones, on the active carbons due to the partial oxidation by O 2 at a definite temperature. The formation temperature of the surface oxides was determined by the thermogravimetric experiment and it depended on the amount and distribution of the inherent oxygen containing groups on the active carbons. Nitric oxide can be completely reduced once the surface oxides are formed at the formation temperature.

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...

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.

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-对话性炭自身的还原性和对NO的还原活性有根重要的影响。对表面富-COO-基团的活性炭,稀盐酸处理使表面-COO-显著分解。浓硝酸处理使活性炭表面含氧量及-COO-基团都明显增加。这是浓硝酸处理使活性炭在较低反应温度下产生较高NO还原转化率的重要原因。对原始活性较差的煤质炭,这种作用表现得更为明显。
