· Industrial and Engineering Chemistry Research
Supercritical water oxidation was applied to the destruction of municipal excess sewage sludge. The reaction was carried out in a batch reactor with hydrogen peroxide as an oxidant in the temperature range of 723--823 K. Ammonia and acetic acid are found to be refractory intermediates in supercritical water oxidation of organic wastes. Ammonia concentration produced during the reaction was measured as a function of reaction time. The dynamic data were analyzed by a first-order kinetics. The reaction rate constant coincides with those reported in the literature.
