Co-oxidation of ammonia and isopropanol in supercritical water in a tubular reactor

Improvements in the ammonia removal were only appreciated with the lowest IPA/NH3 molar ratios (0.125 and 0.25) while the oxygen ratio did not have significant influence in the ammonia removal. Nevertheless, a direct relation between the nitrate concentration and the oxygen in excess was found. Nitrate concentration was also found to increase when the IPA/ammonia ratio increased.
