Ammonia synthesis method and catalyst for ammonia synthesis

Abstract

A method which can efficiently produce ammonia at low temperature and low pressure and which can respond flexibly to an unsteady electrical power supply condition. In addition, a catalyst which is excellent in activity for synthesizing ammonia and which is used in a method for efficiently producing ammonia without regard to supply condition and supply location of electrical power. The method is characterized in that a reactor for synthesizing ammonia is used, and the reactor has a pair of electrodes, a voltage applying means for applying voltage between the electrodes, a catalyst between the electrodes, a raw material gas inlet port, and an ammonia-containing gas discharge port, and including introducing at least nitrogen and hydrogen as a raw material gas into the reactor for synthesizing ammonia, and applying a voltage to the electrodes of the reactor for synthesizing ammonia, wherein electrical discharge does not occur by the voltage.
