| The conversion of natural gas into hydrogen, syngas or liquid hydrocarbons is currently receiving increasing attention. This is in part motivated by the need to utilize natural gas from remote sources and also by novel fuel cell applications. As an alternative method to conventional chemical or catalytic processes, plasmas are studied. However, still a prohibitively high amount of energy is required for plasma excitation. In the current study we investigate the combined operation of a dielectric barrier discharge and a catalyst in the partial oxidation of methane. In order to separate the effects of plasma activation from catalytic processes, the study involves also purely thermal and purely plasma activated operation of the reactor. An enhanced catalytic activity in the presence of the plasma is observed at relatively low temperatures (300°C). In this presentation the effect of the plasma and the catalyst on reactant conversion and product selectivity is discussed and conclusions regarding the underlying mechanism are drawn. |
