The catalytic conversion of the greenhouse gases methane and carbon dioxide was studied in a fluidized bed reactor supported by a RF driven dielectric barrier discharge. The discharge was realized in a coaxial DBD-reactor, driven by a 13.56 MHz power supply unit. Several catalysts powder Pd, Cu, Ag carried by Al2O3, were used supported by a heating system to control the temperature of the catalyst. The mixture of 60% methane and 40% carbon dioxide in Helium as carrier gas was investigated, because it is the average composition of the main components of biogas. The aim was to test whether the biogas composition could by used for the production of synthesis gas. The influence of power rates, catalysts and the temperature of the catalysts on the product yield were studied. The reaction was monitored online by quadrupole mass spectroscopy and infrared spectroscopy supported by a White-cell. The H2/CO ratio could be influenced by using a catalyst and was be found in a area from 1.6 without a catalyst and up to 2.0 by using a Palladium catalyst. The process is highly selective for the hydrogen production (up to 75%, by using the Palladium catalyst).
