Abstract

Catalytic oxidation of environmental contaminants by oxygen has been investigated in water phase at elevated temperatures and pressures. Chlorine and nitrogen containing substances in model solutions, real wastewater of chocolate factory and alcohol plant (-oxygen-containing compounds), petrochemical plant (-sulfurous substances), chemical-recovery plant (-ammonia, sulfurous substances) were used for tests. Initial concentrations of contaminants were up 0.1 to 60 g/l, pH were up 6.0 to 14. In the presence of graphite-like carbons (Sibunits, designed in Boreskov Institute of Catalysis) and Ru/Sibunit the most of substances are oxidized completely at 493-513 K. Among of catalysts of different nature (Pt/Al₂O₃, Fe₂O₃/Al₂O₃, CuCr₂O₄/Al₂O₃, Ru-supported carboneous systems, and Sibunit) the Sibunits are most active and selective, and stable in alkaline medium.
