To provide a new catalyst used for ammonia production.
A catalyst carrier includes 6 barium aluminate. In a method for producing a catalyst carrier, first a surfactant is dissolved in an organic solvent, water is dripped in this solution and emulsion is produced. Then, an aluminium alkoxide, a barium alkoxide and a chelating agent are dissolved in the organic solvent, this organic solvent solution is loaded into the emulsion, and the aluminium alkoxide and the barium alkoxide are hydrolyzed. Next, a crystal of hydroxide is aged at predetermined temperature for predetermined time. Thereafter, a liquid phase is removed, a hydroxide particle is separated, the surfactant is thermally decomposed and then burning is carried out at predetermined temperature for predetermined time. A catalyst carries ruthenium on a carrier. Also, an alkaline metal compound, an alkaline earth metal compound or a rare earth compound can be carried as a promoter. This catalyst is used for an ammonia synthetic reaction.
