Embodiment 1
[0069] Anhydrous liquid ammonia is drawn from the storage tank through the pressure reducing valve, and the flow rate of the ammonia gas reaches 40 milliliters / minute through the control of the flow meter and the regulating valve, and the air inlet 5 ( figure 1) into the plate plasma discharge reactor. The metal plate discharge electrodes 1 and 7 of the reactor are made of ordinary stainless steel, with a diameter of 50 mm and a thickness of 3 mm. The insulating seal 2 between it and the reactor shell is made of polytetrafluoroethylene material, and the distance between the two metal electrodes is 4 mm. An insulating barrier dielectric plate with a surface-center opening of 3 mm is placed in parallel between the two metal electrodes. The insulating medium is made of quartz material with a thickness of 1 mm, and the distance from the high-voltage electrode plate and the grounding plate is 1.5 mm. On the reactor wall between the grounding electrode and the barrier medium plate, ...
Embodiment 2
[0071] Example 1 was repeated, but the discharge parameters were set as follows: the initial voltage of the transformer was 70 volts, and the discharge frequency was 13 kHz. Then the power of the high-voltage power supply reaches 21 watts, the actual discharge voltage is 4.9 kV, the temperature of the reactor is stabilized at 139° C. after the reaction is stable, and the ammonia decomposition conversion rate reaches 47%.
Embodiment 3
[0073] Example 1 was repeated, but the discharge parameters were set as follows: the initial voltage of the transformer was 80 volts, and the discharge frequency was 13 kHz. Then the power of the high-voltage power supply reaches 24 watts, the actual discharge voltage is 5.4 kV, the temperature of the reactor is stabilized at 148°C after the reaction is stable, and the ammonia decomposition conversion rate reaches 52%.
