AC/TiO2 granular photocatalysts optical properties: Material composition effect on the radiative transfer in a photoreactor

The radiative transfer analysis in photoreactor with heterogeneous media is still a challenge for reasons relative to solid particles structural complexity or materials complex optical properties. This article aims study the containing Activated-Carbon/Titanium Dioxide (AC/TiO2) composite particulate media. A focus was made on of photon rate absorbed by these media, which key value further chemical photo-reaction they are intended into system. properties were first consistently defined using different mixing laws refractive index calculation, coupled Mie theory. validation achieved solving equation Monte Carlo algorithm and comparing results transmittance modelling each experiments. second part work consisted use local radiant energy repartition studied access absorbed. These parameters some tools description assessment reactions photoreactor. An originality comes from wide range AC/TiO2 composition through allows analyze evolution properties, as function material composition.
