Prokhorov General Physics Institute of Russian Academy of Sciences Prof. I.A.Kossyi kossyi@fpl.gpi.ru 119991, Vavilov Str. 38, Moscow, Russia photo of group leader • Studied topics • One from the currently important ecological problem consists in utilization of gases accompanying oil recovery. Yearly more than billion cubic meters of associated gases are burning down world-wide • Work performed in General Physics Institute of RAS (GPI) objective is investigation of possibility of natural hydrocarbons (namely CH4) recovery in a liquid (water) plasma-chemical reactors. Two type of reactors have been applied: based on the discharge in a water-gas mixture excited by multispark discharger developed and investigated in GPI and based on the discharge gliding on the water surface (on the water-gas interface). As a working gas methane has been applied. • The first type of reactor has been applied for CH4 decomposition with nanosize carbon and H2 production. The second one has been applied for SYN-gas production. • Record low energy cost for CH4 conversion have been obtained. Physical model explaining the new plasma-chemical reactors peculiarities and advantages has been developed. • Scheme of reactor based on the Scheme of reactor based on the gliding on • multispark discharger. 1-dielectric; the water surface discharge. 1-chamber; • tube; 2-annular electrodes; 3-working 2,3-electrodes; 4-water; 5-CH4; 6-valves; • gas (CH4) bubbles; 4-water; 5-plasma; 7-damping volume; 8-gliding discharge • 6-reactor chamber

2. Main experimental/computational facilities • For this work execution GPI has put into operation two experimental setups based on the multispark discharge and on the gliding on the water-gas interface discharge. • Diagnostic system for gas composition before and after treatment has been assembled and adjusted. • Ramified plasmachemical computer program (code) has been developed and applied for liquid plasmachemical reactor description. • Main research collaborations and industrial partners • GPI in the framework of this program cooperated with; • Ltd „PLASMA-PRO“ (Saratov); • Gubkin State University of Oil and Gas (Moscow); • Moscow State University • Main publications • A.M.Anpilov, E.M.Barkhudarov, N.K.Berezhetskaya et al.
