摘　　要：通过对催化裂化(FCC)汽油萃取-光催化脱硫连续工艺中光催化脱硫反应器的研究,从光的量子性出发,在对FCC汽油光催化脱硫反应器进行合理简化的基础上,建立了光催化脱硫反应器的数学模型.采用隐式差分法对模型求解,求得FCC汽油光催化脱硫反应器中硫化物的浓度、反应温度、光强在径向和轴向的分布.同时,建立了管式光催化反应器中辐射能传递的基本方程和局部体积能量吸收速率的理论模型.并以催化裂化汽油萃取-光催化脱硫连续试验数据验证了模型的可行性.Mathematical model of photocatalysis-oxidation reactor has been investigated for desulfurization of light oil by continuous extraction and photocatalysis-oxidation techniques. A mathematical model of photocatalysisoxidation reactor has been established according to photon quantum absorption theory, and reasonable predigest is suggested. At the same time, the basic equation of radio-technology transfer and Local Volumetric Rate of Energy Absorption model are introduced in the photochemical reactor. The model is suitable for our experimental data of photocatalysis-oxidation desulphurization.
