On the basis of the two-flux model of radiative transfer in photochemical reactor, the model was extended by considering light transmission passing through the photocatalyst, and light was reflected and absorbed by the photocatalyst in the plane parallel-plate reactor. The extended model shows the dimensionless radiation intensity distribution and the dimensionless total radiative energy absorption rate in heterogeneous photoreactor. Semiconductor ultrafine TiO2 power was widely used as the photocatalyst in heterogeneous photochemical reactor for environmental control. In order to show the usefulness of this simple method, the effects of TiO2 power diameter and reactor depth on the dimensionless radiation intensity distribution and on the dimensionless total radiative energy absorption rate in gas-solid heterogeneous photocatalytic reactor were illustrated. The model explains that it is necessary to select reasonable reactor depth, particle diameter and density on semiconductor heterogeneous photoreactor designed.
