用流动法对在裂化催化剂再生的温度、压力及CO,O_2和H_2O浓度条件下CO的气相氧化动力学进行了研究,发现在上述条件范围内的反应可根据温度及水汽浓度为三个动力学区域:低温反应区、水影响反应区及高温反应区。在低温反应区水汽对反应无影响,而在其它两区水汽对反应有较大影响。本文分别给出了这三个区域的动力学方程。
The gas-phase oxidation kinetics of CO under the conditions of temperature, pressure and concentrations of CO, O_2 and H_2O was studied by flow method. It was found that the reaction in the above conditions ranged from three kinetics to temperature and water vapor concentration Area: low temperature reaction zone, water impact reaction zone and high temperature reaction zone. In low temperature reaction zone, water vapor has no effect on the reaction, while in the other two zones water vapor has a greater impact on the reaction. In this paper, the dynamic equations of these three regions are given respectively.
