In the present work, an extended wavelength light absorption spectrum TiO2 type commercially available (Kronos vlp 7000), doped with carbon, is studied for the photocatalytic degradation of a representative VOC under visible light. The photocatalytic reaction of acetaldehyde was studied varying the main parameters of the system, such as the flow rate, relative humidity, pollutant level, and radiance. Complementarily, the modeling of the studied system was carried out, including the kinetic expression for the acetaldehyde degradation and main intermediates generation, the mass balance in the continuous reactor and the lamps emission model for the radiation distribution in the system.
