Abstract
Nitric oxide is formed by the oxidation of ammonia. An ammonia containing gas is contacted with an oxidation catalyst deposited on a surface of a solid electrolyte while an oxygen containing gas is contacted with a second catalyst capable of dissociating oxygen gas to oxygen ion deposited upon a second surface of the solid electrolyte. Oxygen ion is transported through the solid electrolyte to react with ammonia to form nitric oxide under simultaneous production of electric energy.
Claims10
The process for oxidizing ammonia to form nitric oxide which comprises passing an ammonia-containing feed gas at a temperature between about 500.degree. C. and about 1000.degree. C. in contact with a first catalyst deposited on a first surface of a solid electrolyte and passing an oxygen-containing gas in contact with a second catalyst deposited on a second surface of said solid electrolyte, said first catalyst being capable of promoting the oxidation of ammonia to nitric oxide, said second catalyst being capable of dissociating oxygen gas to form oxygen ions, said solid electrolyte being capable of transporting said oxygen ions to contact said ammonia to form nitric oxide.
