(a) LVREA inside the Photoreactor vs. DP25 loading. (b) Overall reaction rate forphenol degradation vs. DP25 concentration.Additionally, MC simulations allowed the determination of the optimal catalystconcentration inside the reactor. It can be seen in Figure 2 that the maximumreaction rate for phenol degradation occurs at the maximum LVREA found withMCM. MCM is an efficient tool in finding the LVREA for a photocatalytic reactor.References[1]. de Lasa, H.; Serrano, B.; Salaices, M. Photocatalytic Reaction Engineering. Springer: New York,2005.[2].
