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 3
Variation of K1 and K2 parameters, expressed in (ppm C)−1 (see kinetic modeling in
Experimental), as a function of flow rate (m3h−1), for
photomineralization of methane in air, and experiments carried out at a fixed
irradiance corresponding to 0.30 Wcm−1. The mean values of k1 and k2 parameters, resulting from modeling of these same
experiments, were sensibly constant ppm Cmin−1; ppm Cmin−1), independently on values of flow rates.
Photocatalytic membranes used in the relative experiments did not contain any
photopromoting agent.
