Hydrogen production and heat transfer distributions of ammonia decomposition in an atmospheric pressure plasma plate reactor

Abstract

This study extensively investigated the hydrogen production and heat transfer distribution in atmospheric pressure dielectric barrier discharge plasma reactor. Ammonia gas was fed into a plasma plate reactor at flow rates of 0.1-1 L/min with different electrode gap distances of 1 mm and 4.5 mm. The heat transfer distribution was determined for the metallic and dielectric electrodes. The maximum conversion rates of the reactor with electrode gap distances of 4.5 mm, 1 mm were 83% and 19.2%, respectively. At a reactor electrode gap distance of 4.5 mm, the maximum energy efficiencies were 0.193%, 0.178%, and 0.105% at ammonia input flow rates of 1, 0.5, and 0.1 L/min, respectively. The results at an electrode gap distance of 1 mm were 0.042%, 0.038%, and 0.022% at ammonia input flow rates of 1, 0.5 and 0.1 L/min, respectively.
