Abstract: The present work describes highly efficient hydrogen production from ethanol in a plasma-catalytic reactor depending on the discharge power and catalyst bed temperature. Hydrogen production increased as the power increased from 15 to 25 W. A further power increase to 35 W did not increase hydrogen production. The catalyst was already active at a temperature of 250 °C, and its activity increased with increasing temperature to 450 °C. The further temperature increase did not increase the activity of the cobalt catalyst. The most important advantage of using the catalyst was the increased ethanol conversion to CO 2 instead of CO production. As a result, the hydrogen yield was very high and reached 4.1 mol(H 2 )/mol(C 2 H 5 OH). This result was obtained with a stoichiometric molar ratio of water to ethanol of 3.
