Catalytic oxidation of environmental contaminants by oxygen has been investigated in water phase at elevated temperatures and pressures. Phenol, aniline, chlorine- and nitrogen containing substances in model solutions, real wastewater of the alcohol plant (oxygen-containing compounds) and petrochemical plant (sulfurous substances) were used in our experiments. Initial concentrations of contaminants were 0.1 - 60 g/1, pH - 6 - 14. In the presence of graphite-like carbons (Sibunits, designed in Boreskov Institute of Catalysis) and supported on Sibunits Ru - catalysts the most of substances are oxidized completely at T=l00-250 °C.
