多相光催化反应器中的辐射能传递研究

Study on radiation transport in heterogeneous photocatalytic reactor

近二十年 ,多相光催化反应在环境方面的应用研究已取得较大的发展。研究主要集中于阐明反应机理和反应路径 ,而对光催化反应器的辐射能传递研究较少。文章介绍了在光催化反应器中辐射传递的基本方程和计算局域体积辐射能吸收速率的理论模型 ,并阐述、分析了验证这些理论模型的实验设计。

Heterogeneous photocatalytic reactions have archieved c onsiderable developmet in study of environment application in the last two deca des. The research has been mainly devoted to elucidating reaction mechanisms and reaction paths. Ther e has been few effort in study from the elucidating radiation transport in photo catalytic reactor of view. This paper introduces the general equation describing radiative transo port and the models calculating the local volumetric rate of r adiative energy absorption (LVREA), and describes and explains experimental vali dation of these models.
