ABSTRACT:
Hydrogen cyanide or ammonia present in a gaseous stream is decomposed catalytically in the presence of oxygen at relatively low temperature by contact with carbonaceous adsorbents doped with oxides of first row transition metals, silver or lanthanide elements, preferably with cobalt, chromium, manganese, silver, and cerium, in the presence or absence of a gaseous reducing agent such as a hydrocarbon or a volatile carboxylic acid.
