    • In a method by which hydrogen supplied as a combustion aid to an ammonia combustion engine is produced from ammonia, the filling amount of a decomposition catalyst in an ammonia decomposition apparatus is reduced. The method includes an ammonia decomposition apparatus that produces hydrogen as a combustion aid and an ammonia oxidation apparatus that allows a part of introduced ammonia to react with oxygen for combustion by action of an oxidation catalyst in order to supply the heat needed for the ammonia decomposition reaction, wherein the amount of ammonia and the amount of air introduced into the oxidation apparatus are controlled in accordance with the entrance temperature of an ammonia oxidation catalyst layer, so as to set the ammonia decomposition ratio in the ammonia decomposition apparatus to be 40 to 60% at all times.
    • 在由氨制造作为燃烧助燃剂的氢气供给的氢的方法中,氨分解装置中的分解催化剂的填充量减少。 该方法包括产生作为燃烧助剂的氢的氨分解装置和氨氧化装置,其允许一部分引入的氨与氧气反应以通过氧化催化剂的作用进行燃烧以提供氨分解反应所需的热量 其中,根据氨氧化催化剂层的入口温度来控制氨的量和引入氧化装置的空气量,以将氨分解装置中的氨分解比设定为40〜60% 每时每刻。

    • Disclosed is an ammonia decomposition catalyst which is obtained by heat-treating a complex at a temperature of 360° C. to 900° C. in a reducing atmosphere, wherein the complex containing a polymer having a molecular weight of 1,000 to 500,000 represented by the formula [I], a transition metal coordinated with the polymer, and an activated carbon or a carbon nanotube added thereto. 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.
