Simulation and optimization of the removal of toluene in air by ozonation with a catalytic open-cell foam

A heterogeneous catalyst, composed of an open-cell glass foam support impregnated with zerovalent ruthenium nanoparticles (loading around 0.1 wt.%), was used to remove toluene in air by catalytic ozonation. Experiments lab-designed 2−6 cm length and 1.6 diameter catalysts were performed. model based on the Langmuir–Hinshelwood mechanism, coupled mass transfer limitations including competitive effects between ozone, designed. It accurately fits experimental data gathered at various temperatures (30−90 °C), gas velocities (0.0025−0.017 m s−1) inlet ozone concentrations (6.4–11.2 g m−3). The removal mainly ruled concentration low while adsorption competition becomes significant high concentrations. Predictive simulations, 1.0 m−3 concentration, compared terms investment cost, operating cost process performances. results highlighted complexity process, which involves antagonist aims design a compact energy-efficient reactor. With best conditions (90 °C 46 concentration), reached 88% (removal rate 0.25 degradation (97%) moderate reactor 0.11 m. These good performances associated catalyst’s synthesis make it efficient alternative for pollutants from air.
