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 1
Kinetics of disappearance
of methane, as substrate, from the gas phase, with 0.30 Wcm−1 of
absorbed radiation power per unit membrane length. Concentrations, in mg/L, for methane, are expressed as carbon, which was not transformed into
intermediates, as a function of time, expressed in minutes, as time necessary
to treat 1 L of gas phase. Photocatalytic membranes used in these experiments
did not contain any photopromoting agent.
