Abstract:
The production efficiency of ammonia is increased while avoiding the necessity for a user to supply water for himself/herself in order to produce the ammonia. An exhaust gas purification apparatus comprises a catalyst (3) which purifies an exhaust gas of an internal combustion engine (1) by using ammonia; and an ammonia supply device (4) which supplies the ammonia to the catalyst (3); wherein the ammonia supply device (4) includes an ammonia producing device (43) which produces the ammonia from nitrogen and water; a nitrogen supply device (44) which separates the nitrogen from air and which supplies the nitrogen to the ammonia producing device (43); and a water supply device (45) which separates the water from the exhaust gas of the internal combustion engine (1) and which supplies the water to the ammonia producing device (43).
