This work is devoted to the plasma steam-reforming of various alcohols: methanol, ethanol and phenol. The plasma reactor is an elementary stationary discharge, which allows us to perform physical diagnostics and chemical analysis of the produced species. The arc is formed between two electrodes made of graphite. The liquid reactants (alcohol + water) are injected in the reactor and are vaporized directly in the upper electrode. Main studied parameters on the gas production are the inlet liquid flow rate, the alcohol mole fraction and the nature of the alcohol. Gas analyses are performed on the outlet gas and the dry gas obtained after a cold trap. From the chemical and the electrical diagnostics, the consumed power to produce 1 kg of H2 is calculated. Main produced species in the dry gas are H2, CO, CO2. CH4 and C2 species are also detected depending on the inlet alcohol in the liquid mixture. To note the effects of the inlet composition of the liquid, we report also the dry gas composition as functions of inlet H/C and H/O ratios.
