Nitrous oxide from nitric acid production

Nitric acid is a key ingredient in N-based fertilizers. As a raw material, it also is used for the production of adipic acid (another important N2O source - see next section) and explosives, metal etching and in the processing of ferrous metals. Nitric acid production involves the oxidation of ammonia (NH3) using a platinum catalyst (Ostwald process). Nitrous oxide forms during the catalytic oxidation of ammonia over platinum rhodium gauzes, the major product being NO. It is estimated that...

The global problem Too much or too little nitrogen

Global Nitrogen Pool Population

Nitrogen, contained in amino acids, proteins and DNA, is necessary for life. While there is an abundance of nitrogen in nature, almost all is in an unreactive form (gaseous nitrogen, N2) that is not usable by most organisms. N compounds fall into two groups - non-reactive and reactive. Non-reactive N is N2. Reactive N (Nr) includes all biologically active, photochemically reactive, and radiatively active N compounds in the atmosphere and biosphere of the earth. Thus Nr includes inorganic...
