A process for producing NO gas from a feed flow of air or oxygen enriched air, by means of moving an electric arc through the air flow by using a magnetic field and AC or DC currents, in a reactor, wherein a pressure lower than 1 bar is applied, wherein the temperature in the exited arc is adjusted to be within the range of 3000 to 5000 Kelvin, and wherein the air flow is quenched by applying a spray of fine water droplets upstream or just downstream the arc, excess air feed or bypassed air to obtain a stable NO-containing plasma having a temperature below 2000 Kelvin. |
