| 摘 要： | 综合光催化氧化苯的动力学过程、光辐射场模型和质量守恒定律,采用平板型反应器建立了碳纳米管/二氧化钛/壳聚糖(CNTs/TiO2/CS)催化薄膜光催化氧化气相苯的数学模型;该模型考虑了光强、相对湿度、初始浓度与气体流速对气相苯光降解的影响。结果表明,建立的数学模型与实验结果吻合较好。

| Abstract: | We combined kinetic process of photocatalytic oxidation of benzene, radiation field model and the conservation of mass. The kinetic reaction rate model was suggested to describe the photocatalytic degradation of gaseous benzene about carbon nano tubes/TiO2/chitosan (CNTs/TiO2/CS) thin films by using plat-plate reactor. The influence of the indoor conditions such as light intensities, relativity humidities, flow rates and initial concentrations was analyzed in this model. Based on the results of calculation and experiments, a good agreement exists between the predictions from the model and the experimental results, which indicates the validity of the proposed kinetic model. |
