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

Figure 2

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 W cm−1 during these runs. Photocatalytic membranes used in these experiments did not contain any photopromoting agent.
