Description:
The production of NO x from air and air+O 2 is investigated in a pulsed powered milli-scale gliding arc (GA) reactor, aiming at a containerized process for fertilizer production. Influence of feed mixture, flowrate, temperature, and Ar and O 2 content are investigated at varying specific energy input. The findings are correlated with high-speed imaging of the GA dynamics. An O 2 content of 40-48% was optimum, with an enhancement of 11% in NO x production. Addition of Ar and preheating of the feed resulted in lower NO x production. Lower flowrates produced higher NO concentrations due to longer residence time in the GA. The volume covered by GA depends strongly on the gas flowrate, emphasizing that the gas flowrate has a major impact on the GA dynamics and the reaction kinetics. For 0.5 L/min, 1.4 vol% of NO x concentration was realized, which is promising for a containerized process plant to produce fertilizer in remote locations. This article is protected by copyright.
