常温常压下氮氢气体放电合成氨的研究

The Study on Synthesizing Ammonia by Nitrogen and Hydrogen Discharge under Room temperature and Normal Pressure

室温常压下，储存在高压钢瓶中的氮、氢气体，流经石英玻璃气套，石英玻璃气套安放在一对圆柱面电极中间，两圆柱面电极与交流电源相连接，电源的输出电压为８～１５ｋＶ，频率为５０Ｈｚ～２０ｋＨｚ。石英玻璃气套中的氮氢气体被高电场强度的交流电场所激活，具有了化学活泼性。常温常压下的气体分子间发生频繁的碰撞可引发化学反应。氮氢气体放电合成了氨（ＮＨ３）。对氮氢气体放电合成氨的转化率影响较大的因素有：１ 放电频率：２ 电源输出电压；３ 氮氢气体混合比。

Under the condition of room temperature and normal pressure,the gas mixture of N 2 and H 2 pass through the silex glass casing.The silex glass gas casing is installed between a pair of cylindrical surface electrodes.The pair of cylindrical surface electrodes is connected with an alternating current power supply whose output voltage is 8～15kV,and whose frequency is 50Hz～20kHz.The gas mixture of N 2 and H 2 in the silex glass gas casing is activated by the high intensity electric field ,and possesses chemical activity.The gaseous molecules unde rroom temperature and normal pressure frequently collide with each other,and may initiate chemical reaction and synthesize ammonia NH 3. The factors which have greater influence on the conversion rate of synthesizing ammonia are:1.discharge frequency.2.utput voltage of the supply source when the frequency of it is fixed at 20kHz.3.mixture ratio of N 2 and H 2.
