(275f) Novel & Optimized Front Photocatalytic Reactor for Toxic Gas Removal: Compactness, Intensification, Efficiency

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.

This study focuses on a new frontal configuration (filter configuration) based on a luminous tissue with LEDs (in-situ). This frontal configuration is known to be less studied in the laboratories. Also, the work addresses the aspect of intensification in terms of number of light fabrics, LED intensities and density of deposited TiO2. On the other hand, the existing literature does not detail any work with this new configuration based on a frontal flow with light fabric and with a reduction of the reactor volume by 70%. Moreover, the literature is mainly devoted to photocatalysis in tangential flow, the few that exist in frontal flow are based on external lighting (UV lamp).

The aim is to study is the photocatalytic treatment efficiency of high concentrations of Cyclohexane in accordance with NIOSH regulations to avoid contact with various parts of the 'respiratory tract' of the body). 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 environments. Also they can give birth to an individual protection device (an autonomous cartridge for a gas mask).

Another new scientific lock has been lifted in this article which is based on the UN Sustainable Development Goals. Indeed, a comparative study in terms of reactor compactness and cost of pollutant removal compared to conventional photocatalysis has been presented.
