【Abstract】 Under the condition of room-temperature and normal pressure,the gas mix-ture of N2 and H2[mixture ratio 1:3,the volume of flow is 40ml/min. (N2) 120ml/ min. (H2)] pass through the silex glass-casing. The silex glass gas-casing is in-stalled between a pair of cylindrical surface electrode. The pair of cylindrical surface electrode are connected with alternating current supply source whose output voltage is 15KV, and frequency is 20 KHz. The gas mixture of N2 and H2 in the siiex glass gas -casing is activated by the high-intensity electric field,and possesses chemical activity. The gaseous molecules under room-temperature and normal pressure fre-quently collide each other, and may initiate chemical reaction and synthesize ammo-nia NH3The factors which have greater influence on the conversion rate of synthesizing ammonia are: (1)discharge frequency, (2)the output voltage of the supply source when the frequency of it is fixed at 20KHz. (3)The mixture ratio of N2 and H2.更多还原
