PP-I-56A STUDY OF LIGHT ALKANE TRANSFORMATIONS IN REACTIVENON-THERMAL PLASMASSuslov A. 1 , Kudryashov S. 2 , Ryabov A. 2 and Kutenkov V. 11 Institute of High Current Electronics, Tomsk, Russia, suslov@to.hcei.tsc.ru2 Institute of Petroleum Chemistry, Tomsk, RussiaThe processes of C 3 -C 4 hydrocarbons (HC) conversion to liquid products hasbeen considered in the glow-type barrier discharge (BD) plasmas at the ambient gastemperature under atmospheric gas pressure. To this end a multi-cell BD-basedreactor system of plane design has been developed with a discharge gap in eachsection of 1 mm in length. A schematic diagram of the experimental assembly (a)with an example of glow-type gas discharge inside single DBD cell (b) are shown inthe figure 1.The C 3 -C 4 mix and gaseous mixtures of C 3 -C 4 with O 2 were studied forproduction of oxygenated and long-chain hydrocarbons. A repetitive pulsed powersupply provided uniform deposition of 1 J of electric energy into reactor with arepetition rate of 1 kHz. The output product concentrations were detected using gasliquidchromatography techniques. To analyze the reaction mechanisms of C 3 -C 4transformations a numerical model of plasma chemical reactor has been developed.It comprised kinetic calculations of conversion processes, a self-consistent simulationof BD and pulsed power supply in conjunction with reactor system. The modelingallowed definition of basic reaction mechanisms and concentrations of the outputspecies.baFig. 1.
