Abstract
Non-catalytic hydrogen production from ammonia gas using a pulsed atmospheric plasma have been developed to solve the problems of hydrogen transportation and storages. Ammonia is easily decomposed by electron energy generated by plasma, which is converted to molecular hydrogen and nitrogen by global reaction; NH_3 + e → 0.5 N_2 + 1.5 H_2. A hydrogen yield attained 100% at an applied voltage of 15 kV and an ammonia flow rate of 0.2 L/min. T o improve the energy efficiency of hydrogen production, a plasma reactor with a hydrogen separator was proposed. As the hydrogen separator was inhibited the reverse reaction for ammonia formation (N + 3H→NH_3), the hydrogen yield attained 100% at an applied voltage of9kV and an ammonia flow rate of0.8L/min..
