Summary
Reaction studies have been carried out on the destruction of nitrogen-containing compounds such as ammonium, nitrates, and species containing aromatic nitro functionality. The destruction of ammonium ion in near-critical and supercritical water using Raman spectroscopy is the subject of this presentation. Reaction rates were determined from Raman spectra and from measurements of system pressure. Concentrations of key species in the reactor effluent were determined via off-line assay. The effects of temperature, pressure, and concomitants on reaction rate were determined. The reaction half-life is below ten seconds at 400 C with better than 95% conversion. Oxides of nitrogen were not generated in detectable quantities. The studied system is a model for the destruction of ammonium in municipal wastes.
