    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 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.

In a case of using the carbon nanotube, an alkali metal compound or an alkaline earth metal compound is added to the heat-treated complex. R1 represents H or hydrocarbon having 1 to 10 carbon atoms, R2 and R3 each represent H, halogen, nitro, acyl, ester, carboxyl, formyl, nitrile, sulfone, aryl, or alkyl group having 1 to 15 carbon atoms, X and Y each represent H or OH, Z represents CH or N, R4 and R5 each represent H, OH, ether, amino, aryl, or alkyl group having 1 to 15 carbon atoms, x represents a real number of 1 to 2, y represents a real number of 1 to 3, and n represents a real number of 2 to 120. The amount of the transition metal deposited on the catalyst can be increased without deteriorating the dispersion of the metal, so that the amount of the catalyst required to obtain a desired activity can be reduced.
