FIELD: chemistry.
SUBSTANCE: invention relates to the chemical industry. Hydrogen sulphide is oxidised by oxygen or air in an installation with an immobile layer of a heterogeneous catalyst on any solid porous carrier at a temperature of 130-200°C and the molar ratio oxygen: hydrogen sulphide 0.5-5. The catalyst, containing 0.5-10 wt % of a complex compound of formula MgCl2·ZnCl2·nEt2O (where n=1-4) is obtained by the impregnation of the solid porous carrier with a solution of the said complex compound in diethyl ether with further drying.
EFFECT: invention makes it possible to increase the sulphur output and selectivity of converting hydrogen sulphide into sulphur.
