PP-III-3HIGH POROSITY CELLULAR METAL IN PLASMACATALYTIC GASTREATMENTAntsiferov V.N., Khanov A.M. 1 , Makarov A.M. 2 , Makarov A.A. 2The Scientific Centre of Powder Material Science, Perm, Russia1 Perm State Technical university, Perm, Russia2 ZAO “ECAT”, Perm, RussiaE-mail: detali@pstu.ac.ruPlasmacatalytic device is developed for sterilization and purification of polluted air.Technology is based on a highly porous cellular metal (HPCM) carrier catalytic blocks anddielectric low-temperature plasma barrier or surface discharge with the use of ceramics andHPCM electrodes.High-porosity permeable cellular metals and alloys represent a new type of structureshaving unsurpassed porosity, permeability and cohesion. The combination of heterogeneouscatalysis and low-temperature plasma technologies (Figure 1) has allowed creation ofcompact high-efficiency plasmacatalytic air cleaning device. Final clearing and fulldecomposition of surplus of ozone occurs on an electrical heating porous nickel catalyticblocks.It is shown, that cold plasma is stably generated on non-uniform surface of HPCM withbarrier and surface discharge mechanism at voltage as low as 2000 V. Highly permeablestructure of HPCM effectively dissipates heat and removes generated ozone in a gas stream.Computer simulation of heat-exchange, electric field, flow regime, temperature and pressureis carried out with the use of a finite elements method. Results of simulation have allowed tooptimize a design and to improve efficiency of clearing and sterilization of air. Pre-productiondevices have shown high efficiency in complete decomposition of organic compounds tocarbonic gas and water and can be used in air conditioning and sterilization in industrial,public and household purposes.AcknowledgementsThe authors are grateful to Foundation for Assistance to Small Innovative Enterprises(FASIE) for financial support of this work (projects 4043p/4931).474
