Plasma-catalytic methanol-steam reforming was investigated in the present study.
A tubular quartz reactor with annular-shaped electrodes was used, in which Cu/ZnO catalysts
supported on Al2O3 pellets were packed. Non-thermal plasma on the catalyst was
generated by an electric discharge. The effect of the temperature, feeding rate, voltage,
frequency, and waveform on methanol conversion was investigated. The methanol conversion
under the electric discharge increased as the discharge voltage and frequency
increased. Square waveform was more effective in methanol conversion than the sine
waveform. The electric discharge provided the sufficient energy to break chemical bonds of
methanol and steam. Moreover, the strong electric field increased absorption intensities of
reactants on the active sites of the catalyst surface
