在13.56赫兹驱动同轴DBD反应器的支撑下，对甲烷和二氧化碳的催化转化进行了研究。催化剂使用的是包覆在氧化铝颗粒上的钯或铜催化剂。目的是测试沼气是否可以用于生产合成气。考察了放电功率、催化剂和催化剂床层温度对产品收率的影响。用四极杆质谱仪和红外光谱仪对原料和产品流进行了分析。H-2/CO比可以在0.65(无催化剂)到1.75(使用铜催化剂)的范围内调整。该工艺对制氢具有很高的选择性(使用钯催化剂，最高可达83%)。将催化剂加热到250℃时，铜催化剂的H-2/CO比从1.04增加到1.16，钯催化剂从1.11增加到1.43。
The catalytic conversion of methane and carbon dioxide was studied in a fluidized bed reactor supported by a 13.56 Hz driven coaxial DBD-reactor. Palladium or cupper catalyst which are covered on Al2O3 particles were used. The goal was to test whether biogas can be used for the production of synthesis gas. The influences of discharge power, catalysts and temperature of the catalyst bed on the product yield were studied. The starting material and product stream was analyzed by quadrupole mass spectrometry and infrared spectroscopy. H-2/CO ratios can be adjusted in a range between 0.65 (without a catalyst) and 1.75 (using a copper catalyst). The process is highly selective for hydrogen production (up to 83%, using a Palladium catalyst). A copper catalyst increases the H-2/CO ratio can from 1.04 to 1.16 and the palladium catalyst from 1.11 to 1.43 by heating the catalyst to a temperature of 250A degrees C.
