METHOD OF CATALYTIC DESULFURIZATION OF GAS CONTAINING COMPOUNDS HS AND SO AND CATALYST FOR ITS REALIZATION Russian patent published in 1999 - IPC

FIELD: chemical technology, inorganic chemistry. SUBSTANCE: invention relates to desulfurization of gases containing H₂S and SO₂ and if necessary compounds COS and CS₂. Gas is contacted with a catalyst formed by CATALYTIC phase associated with silicon carbide as a carrier consisting of at least 40% of the catalyst mass. The process is performed at temperatures that can be above or lower of the dew point of sulfur formed in reaction gases and depending on conditions of the method realization. Invention ensures to desulfurize gas at the improved selectivity by sulfur. EFFECT: improved method of desulfurizing. 18 cl, 5 tbl, 4 ex
