Abstract: Basic principles are considered concerning the action of photocatalysts in deep oxidation of organic compounds containing in air. Within the framework of the Langmuir-Hinshelwood model, kinetic parameters were calculated concerning the photo-oxidation process for a number of substances (the rate constant and adsorption constants) were then used for designing reactors for air purification. It is demonstrated that for increasing the rate of photocatalytic oxidation it is necessary to optimize the geometry of a photocatalytic filter, as well as to use inorganic air-penetrable materials (glass fibre cloth and foamed ceramics) as carriers for a photocatalyst. In addition, the efficiency of air purification could be enhanced through the use of multi-stage reactor wherein air under purifying passes successively the stages of electrostatic filtration, adsorption and photocatalytic treatment. An example of the proposed concept of multi-stage air purification was demonstrates at the Luch Co. (Novosibirsk).
