To date, methane is the most commonly adopted hydrocarbon for H2 generation. Apart from conventional processes of methane reforming, plasma processing is a new efficient technique, which can be used for converting hydrocarbons and organics into syngas. Most of published investigations on hydrocarbons plasma reforming are based on non-equilibrium, non-thermal plasmas. Comparing with that by non-thermal plasmas, the CH4 reforming by thermal plasma exhibits the significant advantages like large treatment capacity, little byproducts, and relatively high energy conversion efficiency. In this work we studied dry and steam methane reforming in steam thermal plasma with substantially higher arc power than in up now published experiments. Experiments were performed on plasma reactor PLASGAS equipped by plasma torch with a dc arc stabilized by combination of argon flow and water vortex1,2. The measuring system included monitoring of plasma torch operation parameters, temperatures in several positions inside the reactor and calorimetric measurements on cooling water loops. The composition of produced gas was measured on line by a quadruple mass spectrometer at the output of quenching chamber positioned after the reactor. The flow rate of produced syngas was determined from molar concentration of argon when defined amount of argon was introduced into the reactor. Reaction of methane with CO2 and water injected into steam plasma flow was studied for the torch power 88 to 136 kW and methane flow rates 75 to 150 slm. CO2 and water were added to reach molar ratio C/O equal 1 at the input reactants. The output H2/CO ratio could be adjusted by a choice of feed rates of input reactants in the range 1.1 to 3.4. Depending on experimental conditions the conversions of methane and carbon dioxide were 82 - 99.7% and 89 - 93%, respectively, the selectivity of CO and H2 was 87 - 99.9% and 82 - 98%, respectively, and the energy needed for production of one mole Pracoviště Ústav fyziky plazmatu Kontakt Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Rok sběru 2018
