OXIDATION OF AMMONIA CATALYZED BY MIXED OXIDES OF COPPER AND CHROMIUM

Abstract

The oxidation of ammonia catalyzed by cupric chromite (CuCr2O4) and cuprous chromite (Cu2O . Cr2O3) has been studied in order to examine the role of the copper ion valence state. The results at 400C indicate that Cu(2+) is a much better catalyst for this reaction in which nitrogen is the major product. Similar considerations apply to the complete oxidation of olefinic hydrocarbons. It is suggested that cupric chromite, commonly employed as an ignition and burning-rate catalyst for ammonium perchlorate solid propellants, plays the dual function of catalyzing the decomposition of ammonium perchlorate and the oxidation of ammonia and fuel molecules.
