Photocatalytic oxidation within reactors, as a promising method from economical and environmentally friendly points of view, is used to VOC treatment; and among various types of reactor, the fluidized bed reactor as an efficient reactor is employed for this aim. Modeling and simulation of photocatalytic fluidized bed reactors are essential for scale-up, optimization, and control. In this study, Methyl Ethyl Ketone (MEK), TriColor Ethylene (TCE), and toluene were considered as pollutant models, and photocatalytic conversion of these chemicals in the fluidized bed reactor was simulated. In order to simulate the performance of the photocatalytic fluidized bed reactor, the kinetic sub-model and the hydrodynamic sub-model were coupled together and solved simultaneously.  The Langmuir-Hinshelwood (LH) kinetic model was adopted for photocatalytic conversion of pollutants and its kinetic parameters were determined experimentally. The dynamic two-phase models were considered as the hydrodynamic sub-model and its validity was investigated through comparing the simulation data and the experimental results. It was observed that there is close agreement between the model and the experimental data. The modeling and simulation results of this study can be used to predict the performance of the photocatalytic fluidized bed reactor.
