FIELD: method of desulfurization of waste gases; power engineering, chemical industry, ferrous and non-ferrous metallurgy.
SUBSTANCE: proposed method includes heterogeneous-catalytic oxidation of sulfur dioxide contained in flue gases and absorption of sulfuric anhydride formed during this procedure by water. Used as catalyst are ferrospinels prepared on base of manganese-zinc powder in form of thin plates which are constantly crushed directly in zone of oxidation of SO2 and SO3 in aqueous medium continuously generating freshly formed catalytically active surfaces. Process is performed under normal conditions: room temperature and atmospheric pressure.
EFFECT: enhanced efficiency.
