Description
<p>One-step ammonia synthesis under ordinary temperature and pressure has been attempted by introducing a nitrogen source (pure nitrogen gas or air) to hydrogen production reaction field of in-liquid plasma. As a result of the experiment, it was confirmed that ammonia can be synthesized by this method. However, the amount of ammonia synthesized was small. Most of the produced hydrogen is as pure. Also, the introduced nitrogen source is almost released outside of the reactor. This indicates low ammonia selectivity, study is required to improve the selectivity. The findings of this study are that the hydrogen production efficiency (HPE) and the C O balance of the raw materials affect the amount of ammonia synthesized. It was found that the higher HPE the better. A one to one ratio of C and O was found to be the optimal condition.</p>
