Influence of Irradiance, Flow Rate, Reactor Geometry, and Photopromoter Concentration in Mineralization Kinetics of Methane in Air and in Aqueous Solutions by Photocatalytic Membranes Immobilizing Titanium Dioxide

Kinetics of disappearance of total organic carbon (TOC) from gaseous methane in the laboratory-scale photoreactor (see Experimental), expressed as concentrations, in mg/L of carbon, which was not mineralized, as a function of time, expressed in minutes, as time necessary to treat 1 L of gas phase. Absorbed radiation power per unit membrane length was 0.30 Wcm⁻¹ during these runs. Photocatalytic membranes used in these experiments did not contain any photopromoting agent.
