Abstract:
1. An ammonia synthesis apparatus comprising: a first gas channel; a second gas channel disposed outside the first gas channel; a third gas channel disposed outside the second gas channel; an air supply unit that supplies air to the second or third gas channel; a water supply unit that supplies water to the first gas channel; and a heat supply unit that supplies heat to the first gas channel, wherein a metal or a metal oxide that reduces water so as to produce hydrogen is placed in the first gas channel; wherein a downstream end portion of the second gas channel is located downstream of a downstream end portion of the first gas channel; wherein an ammonia synthesis catalyst for synthesizing ammonia from hydrogen and nitrogen is placed in a portion of the second gas channel which is located downstream of the downstream end portion of the first gas channel; and wherein the second gas channel and the third gas channel are at least partially partitioned by an oxygen permeation membrane that selectively allows oxygen to permeate therethrough, or a nitrogen permeation membrane that selectively allows nitrogen to permeate therethrough, so that oxygen is supplied to the third gas channel, and nitrogen is supplied to the second gas channel.
