Sažetak
The reaction kinetics of the photocatalytic oxidation of oxalic acid over irradiated TiO2(Degussa P25) in a slurry, annular photocatalytic reactor was studied. Experiments were carried out at different photon fluxes and different concentrations of oxalic acid (10, 20 and 40 mg L−1). The results were analyzed in terms of a comprehensive kinetic model of the photocatalytic oxidation of oxalic acid, including the explicit effect of photon absorption. Integration of a full model of the photocatalytic reactor and the oxidation of oxalic acid was accomplished by modelling the radiation field in the reactor with the Six-Flux Absorption-Scattering Radiation Model (SFM)* which allows an integral analytical estimation of the local volumetric rate of photon absorption (LVRPA) at each point of the reactor.
