Zusammenfassung:	Disclosed is a method of substantially completely oxidizing material in an aqueous phase at supercritical temperatures and sub- or supercritical pressures by initiating the oxidation in the presence of small amounts of strong oxidizing agents that function to increase the initial reaction rate for the oxidation. The strong oxidizing agents suitable for use in the present invention comprise at least one selected from the group consisting of ozone (O3), hydrogen peroxide (H2O2), salts containing persulfate (S2O8), salts containing permanganate (MnO4), nitric acid (HNO3), salts containing nitrate (NO3), oxyacids of chlorine and their corresponding salts, hypochlorous acid (HOCl), salts containing hypochlorite (OCl), chlorous acid (HOClO), salts containing chlorite (ClO2), chloric acid (HOClO2), salts containing chlorate (ClO3), perchloric acid (HOClO3), and salts containing perchlorate (ClO4). L'invention concerne un procédé d'oxydation pratiquement totale d'une matière, en phase aqueuse, à des températures surcritiques et des pression sous- ou surcritiques. Ledit procédé consiste à déclencher l'oxydation en présence de petites quantités d'oxydants puissants destinés à augmenter la vitesse de réaction initiale du processus d'oxydation. Les oxydants puissants appropriés selon l'invention contiennent au moins un oxydant du groupe comprenant l'ozone (O3), le peroxyde d'hydrogène (H2O2), des sels contenant du persulfate (S2O82-), des sels contenant du permanganate (MnO4-), l'acide nitrique (HNO3), des sels contenant du nitrate (NO3-), des oxyacides de chlore et leurs sels correspondants, l'acide hypochloreux (HOCl), des sels contenant de l'hypochlorite (OCl-), l'acide chloreux (HOClO), des sels contenant du chlorite (ClO2-), l'acide chlorique (HOClO2), des sels contenant du chlorate (ClO3-), l'acide perchlorique (HOClO3) et des sels contenant du perchlorate (ClO4-).
