[en] Reforming of gaseous and liquid hydrocarbon compounds into hydrogen is of high interest. In this paper we present a microwave (2.45 GHz) plasma-based method for hydrogen production by conversion of ethanol (C₂H₅OH) in the thermal reforming process in nitrogen plasma. In contrast to our earlier investigations, in which C₂H₅OH vapour was supplied into the microwave plasma region either in the form of a swirl or axial flow, in this experiment we injected C₂H₅OH vapour directly into the nitrogen microwave plasma flame, behind the microwave plasma generation region. The experimental results were as follows. At an absorbed microwave power of 5 kW, N₂ (plasma-generating gas) swirl flow rate of 2700 NL(N₂)/h and C₂H₅OH mass flow rate of 2.7 kg(C₂H₅OH)/h the hydrogen production rate was 1016 NL(H₂)/h, which corresponds to the energy yield of hydrogen production 203 NL(H₂)/kWh. After the C₂H₅OH conversion the outlet gas contained 27.6% (vol.) H₂, 10.2% CO, 0.2% CO₂, 4.8% CH₄, 4.3% C₂H₂, 3.7% C₂H₄ and 3.7% C₂H₆. These results are comparable to those obtained in our earlier investigations, in which different methods of C₂H₅OH vapour supply to the microwave plasma generation region were employed.
