摘　　要：介绍了微管反应器和微管内环己烷氧化反应的特点;详述了微管内环己烷无催化氧化的反应工艺、微管内气液流动情况、反应机理以及微管内壁负载催化剂的环己烷催化氧化反应工艺;指出无催化及内壁涂覆催化剂的微管内环己烷氧化反应在改善反应的安全性、强化气液传质效果和提高催化性能等方面具有较大优势,微管内壁负载纳米金催化剂的反应器形式在环己烷氧化反应中前景看好。A micro-capillary reactor and the characteristics of cyclohexane oxidation in the micro-capillary reactor were introduced. The reaction process and mechanism of non-catalyst cyclobexane oxidation in the micro-capillary reactor were described in details, as was the flow characteristics of gas-liquid phase in the micro-capillary reactor. And the technology of cyclobexane oxi- dation catalyzed with the supported catalyst coated on the wall of the micro-capillary reactor was also described. The technologies of cyclohexane oxidation without catalysts or with the catalyst coated on the wall of the micro capillary reactor were significantly superior in improving the reaction safety, intensifying the gas-liquid mass transfer and bettering the catalyst performance. The reactors with supported nano-gnld catalysts on the wall of the micro-capillary reactor were expected to have an attractive prospect for eyclohexane oxidation.
