Embodiment 1
[0083] Cyclooctane is oxidized using the method described above and using the system, wherein:
[0084] The gas-liquid ratio of alkane to oxygen in the micro-interface generator is 270:1, the catalyst in the reactor is a molybdenum-nickel catalyst, the temperature is 300°C, and the space velocity of the gas-liquid emulsion is 0.8h -1 , the pressure is 0.01atm.
[0085] Analyzing the products after the reaction, it can be obtained that the conversion rate of unsaturated alkanes in this example is 34.5%, and the selectivity is 95.9%.
Embodiment 2
[0087] Undecane was oxidized using the method described above and using the system, wherein:
[0088] The gas-liquid ratio of alkanes and oxygen in the micro-interface generator is 450:1, the catalyst in the reactor is a carbon-supported iron-based catalyst, the temperature is 500°C, and the space velocity of the gas-liquid emulsion is 1.2h -1 , the pressure is 2.5atm.
[0089] Analysis of the reacted product shows that the conversion rate of unsaturated alkanes in this example is 31.7%, and the selectivity is 94.8%.
Embodiment 3
[0091] Pentadecane was oxidized using the method described above and using the system, wherein:
[0092] The gas-liquid ratio of alkane to oxygen in the micro-interface generator is 600:1, the catalyst in the reactor is a molybdenum-cobalt catalyst, the temperature is 750°C, and the space velocity of the gas-liquid emulsion is 1.5h -1 , the pressure is 5atm.
