CATALYST FOR OXIDATION OF SULFUROUS COMPOUNDS Russian patent published in 1997 - IPC

FIELD: production of heterogeneous catalysts of liquid phase oxidation of sulfurous compounds (sulfur dioxide, hydrogen sulfide, mercaptans); purification of gas exhaust and sewage of energetic, oil processing, petrochemical, chemical and pulp and paper industries. SUBSTANCE: heterogeneous catalyst for oxidation of sulfurous compounds comprises supported active component, high pressure polyethylene being used as carrier. Pyrolisite ore is proposed as active component. Said ore comprises, mas. %: magnesium oxide (IV), 54.76-69.10; magnesium oxide(II), 1.80-4.85; ferrum oxide (III), 5.00-11.23; silicium oxide, 4.05-7.52; barium oxide, 3.95-5.02; aluminium oxide, 0.92-5.03; titanium oxide, 0.01-0.03; calcium oxide, 0.50-0.82; manganese oxide, 0.40-0.70; potassium oxide, 2.87-3.10; sodium oxide, 0.37-0.58; phosphorous oxide (V), 1.10-1.35. Proposed catalyst comprises, mas. %: pyrite cinder, 8-10; copper oxide (II), 5-10; pyrolisite ore, 20-25; polyethylene, the balance. EFFECT: improved quality of desired product. 1 tbl
