Abstract
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.
