中文摘要：

通过吸附穿透曲线和吸附容量，考察了两种活性炭吸附剂在不同气氛条件下SO2和NO的常温吸附性能．结果表明，无氧条件下，活性炭对NO吸附能力较弱；有氧时，O2可促进NO在活性炭上的吸附转化；无氧条件下，活性炭吸附SO2的性能远远强于吸附NO；O2的存在均可提高两种活性炭对No和SO2的吸附能力．预吸附NO形成的某些NOx物种可促进SO2吸附．SO2对NO的吸附有明显抑制作用．同时吸附时，SO2和NO不会单独占据同一活性中心，即S02与NO可能有共同的吸附位，并形成新的吸附态中间产物．且比较两种活性炭的常温吸附性能，椰壳活性炭强于煤质活性炭．

英文摘要：

The characters of two types of activated carbon absorbents in the processes of NO and SO2 adsorption at room temperature were investigated by adsorption breakthrough curve and adsorption capacity in this work. The results show that, in the absence of O2, the adsorptive capability for NO of these two activated carbon absorbents are extremely weak. Obvious improvement of NO adsorption could be observed in the adsorption process under the O2-attendance conditions. For individual component adsorption, the two sorbents show a higher adsorption capacity in SO2 than in NO, and the presence of O2 could promote the adsorption both NO and SOs. Coal activated carbon has better capacity of absorbing SO2 and the process might be promoted by certain species produced by NO pre-adsorption. SO2 has an inhibiting effect on NO adsorption. In the simultaneous adsorption of NO-SO2-05, NO and SOs may not occupy the same active site independently. It means that new adsorbed intermediate species may formed during the co-adsorption of NO-SO2-O2. The coconut shell activated carbon performed better than the coal activated carbon in the co-adsorption process at room temperature.
