text: As a result of extensive researches carried out to develop a process for selectively converting nitrogen dioxide into nitrogen monoxide at a lower temperature, it has now been found that nitrogen dioxide in a reaction gas can be converted selectively and quantitatively into nitrogen monoxide by passing the gas containing nitrogen dioxide through a certain type of a reaction composition which is mainly comprised of a metal carbide in which the metal and carbon are chemically bonded.
