PCT No. PCT/SU87/00083 Sec. 371 Date Jun. 2, 1988 Sec. 102(e) Date Jun. 2, 1988 PCT Filed Jul. 27, 1987 PCT Pub. No. WO88/02736 PCT Pub. Date Apr. 21, 1988.The present invention relates to the production of elemental sulphur from sulphur dioxide and hydrogen sulphide by the Claus reaction. To obtain elemental sulphur, into a catalyst bed divided into at least two parts the reaction gas having temperature of not less than 120 DEG C. is introduced in the direction perpendicular to the cross-section along which the catalyst bed is divided. At least into one part of the catalyst bed sulphur dioxide and hydrogen sulphide are introduced at a temperature below the dew point of sulphur. Between parts of the catalyst bed resulting from its division intermixing and/or cooling of the reaction gas is effected. In at least one part of the catalyst bed the direction of supply of the reaction gas is reversed when the difference in temperatures of this gas at the inlet and outlet of the second part of the catalyst bed reaches 50 DEG -150 DEG C. Gaseous sulphur formed as a result of interaction of the reaction gas with the catalyst is withdrawn from the catalyst bed and subjected to a further condensation.
