Hydrogen production from ammonia using a microwave plasma torch at atmospheric pressure
- An electrodeless, catalyst-free microwave (MW) plasma torch has been investigated to produce hydrogen (H2) from ammonia (NH3) dissociation, with NH3 admixed in nitrogen up to 90 vol.% using a total inlet flow rate of 10 sLm at atmospheric pressure. Conversions beyond 99% are obtained for MW powers between 1.50 − 1.75 kW. The largest H2 energy yield ≃ 447 LH2 kWh−1, or lowest energy cost of 25 kWh kg−1 H2, is obtained for 90 vol.% [NH3], which corresponds to outlet concentrations of H2 and NH3 around 69 vol.% and below 1 vol.%, respectively. These performances are highly promising for the application of plasma technology for the production of hydrogen from ammonia.
