| Abstract: | Mixtures of CO und H2 can be partially converted into hydrocarbons (Hc), especially methane, by nonthermal activation in a glow discharge. The degree of conversion α CO → Hc and the partial pressure of methane reached values of 12% and 3% resp. The CO-conversion depends on the discharge parameters, the discharge time the energy input resp., and the rate of CO/H2-mixture. The Hc formed are intermediate products which react further to higher Hc including solid Hc. According to mass spectrometrical analysis of plasma ions a reaction scheme was developed which is considered to be valid for the Hc formation based on an ion as well on neutral particle reactions. |
