A method for preparing ammonia using plasma
The plasma chemical chain synthesis process for ammonia utilizes a plasma field to activate nitrogen gas and react it with alkaline (earth) metal hydrides. The process involves two steps: nitrogen fixation and hydrogenation, which solves the problems of high energy consumption and low catalyst efficiency in existing technologies and achieves efficient ammonia synthesis under mild conditions.

AI Technical Summary
Existing industrial ammonia synthesis processes are characterized by high energy consumption, large carbon emissions, and no significant improvement in catalyst efficiency. Furthermore, the reaction conditions are harsh, making it difficult to synthesize ammonia efficiently under mild conditions.
The plasma chemical chain synthesis process for ammonia involves activating nitrogen gas in a plasma field to react with alkaline (earth) metal hydrides in two steps: nitrogen fixation and hydrogenation, to generate NH3. A transition metal catalyst is used to enhance the activity.
This method achieves efficient ammonia synthesis under normal pressure, reduces energy consumption, increases ammonia production rate, and is simple to operate, thus having broad research and application prospects.
