    摘要： The invention provides a process for efficient synthesis of ammonia. The process includes a water-splitting step in which water is decomposed to obtain a first source gas comprising hydrogen and oxygen, a first oxygen removal step in which the oxygen contained in the first source gas is at least partially separated and removed by an oxygen separating membrane or hydrogen separating membrane to obtain a second source gas having a lower oxygen concentration than the first source gas, a second oxygen removal step in which the oxygen in the second source gas is reacted with hydrogen to produce water for removal, or is adsorbed onto an adsorption medium for removal, to obtain a third source gas having a lower oxygen concentration than the second source gas, and an ammonia synthesis step in which the hydrogen in the third source gas is reacted with nitrogen to synthesize ammonia.

    摘要： An apparatus and method purify hydrogen from a mixed fluid containing gaseous hydrogen, gaseous oxygen, and liquid water. The apparatus has a mixed fluid channel through which the mixed fluid flows; a first gas channel through which a mixed gas containing gaseous hydrogen and gaseous oxygen flows; a second gas channel through which gaseous hydrogen or oxygen flows; a gas-liquid separating membrane forming a wall between the mixed fluid channel and the first gas channel, separating the mixed gas from the mixed fluid of the mixed fluid channel, and providing the separated mixed gas to the first gas channel; and a hydrogen or oxygen separating membrane forming a wall between the first gas channel and the second gas channel, separating gaseous hydrogen or oxygen from the mixed gas of the first gas channel, and providing the separated gaseous hydrogen or oxygen to the second gas channel.

    摘要： An ammonia synthesis apparatus includes: 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. A metal or a metal oxide that reduces water to produce hydrogen is placed in the first gas channel. An ammonia synthesis catalyst is placed in the second gas channel located downstream of the downstream end portion of the first gas channel. The second and third gas channels are at least partially partitioned by an oxygen permeation membrane, or a nitrogen permeation membrane, so that oxygen is supplied to the third gas channel, and nitrogen is supplied to the second gas channel.
