| 制备并研究了几种负载型ＣｕＣｌ体系中ＣｕＣｌ的分散状态及其ＮＯ分解性能。结果表明，单层分散对于负载型ＣｕＣｌ体系的Ｎ粉解性能起着重要作用。ＣｕＣｌ含量在其分散阈值附近的样品具有最高的ＮＯ解解活性。 |
| 英文摘要: |
| Several supported CuCl systems were prepared and studied by XRD, their NO decomposition behaviour were measured with a microreactor. The results showed that monolayer dispersion played an important role in the NO decomposition activity of supported CuCl systems. Samples with CuCl contents near their monolayer dispersion capacities showed the highest activity, the higher the surface area of the support, the higher the CuCl dispersion capacity, and hence, the higher the activity of the sample. By dispersing CuCl on high surface area supports prepared by supercritical drying technique, we got samples with 55%~60% conversion of NO to N 2 at 773 K and 6 000 h -1 . |
