Experimental assessment of a combined plasma/catalytic system for hydrogen production via partial oxidation of hydrocarbon fuels

A combined reformation system, which includes both auto-thermal catalytic and non-equilibrium plasma units, is studied experimentally. The system is assessed for the practical application of hydrogen production via reforming of liquid gasoline-like fuels. The catalyst has been previously used for reforming of different types of hydrocarbons, demonstrating good performances in terms of hydrogen production for temperatures as high as 800°C. In this work, a non-equilibrium plasma source is coupled to the catalytic unit. A pulsed corona reactor is used as a non-equilibrium plasma source at atmospheric pressure. The performances of combined reformation system are characterized experimentally in terms of hydrogen yield and electric power consumption. Hydrogen conversion and byproduct composition are determined and quantified with respect to power consumption, reactor temperature, input reactant composition, and configuration of the experimental setup.
