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.

EUROPEAN COOPERATION IN SCIENCE AND TECHNOLOGY COST is supported by the EU RTD Framework Programme ESF provides the COST Office through an EC contract www.cost.eu COST Action TD1208 Electrical discharges with liquids for future applications 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.
