(537h) Photocatalytic Process Optimization for Toxic Gases Removal: Mass Transfer Effect Elimination Efficiency of Chemical Weapon Agent (Simulant)

Today, air pollution has become a major environmental concern. Human activities have led to increase contamination in the atmosphere, particularly through the release of a wide variety of volatile organic compounds (VOCs) and toxic gases. To this end, the development of new methods of controlling and treating air pollution has become the primary purpose of research. in this regard, we present an efficient solution for the treatment of toxic gases, based on a destructive process, photocatalysis. A technology that allows the elimination of pollutants by converting them into CO₂ and H₂O. The aim is to study the photocatalytic treatment efficiency of cyclohexane (C₆H₁₂) which is defined as the benchmark for testing the efficiency of type A anti-gas cartridges. A photocatalytic frontal reactor (PFR) with different configuration was used to investigate the influence of air flowrate, mass transfer limitation, Elimination pathway for the high concentrations of Methyl salicylate (2-(HO)C₆H₄CO₂CH₃) simulant of the chemical weapon agent “mustard gas”).

The obtained results confirm that the optimized reactor configuration presents an extremely promising avenue for the treatment of the photocatalysis use in dealing with highly contaminated environments. Also they can give birth to an individual protection device (an autonomous cartridge for a gas mask).
