Abstract
A reactor ( ) is described in which a catalytic reaction, associated with a thermal effect, is performed on substances contained in a gas flow, in particular the recovery of sulphur from gases containing hydrogen sulphide. A housing ( ) of the reactor ( ) comprises a gas inlet ( ) and a gas outlet ( ). Inside the housing ( ) is arranged a bed of catalytically active material, heat being supplied to or withdrawn from said material by means of a temperature regulating device ( ) depending upon the nature of the reaction. The temperature regulating device ( ) is formed by a plurality of tubes ( ) bent in a U-shaped formation. In each case one side of all these U-tubes ( ) leads into a first distribution chamber ( ) which can be supplied with a heat carrier medium. The other side ( ) of the U-tubes ( ) in each case leads into a second distribution chamber ( ) from which the heat carrier medium can be discharged again. The temperature regulating device ( ) thus formed is extremely cost-effective to produce and service; it also facilitates a particularly well defined development of a desired temperature distribution within the catalyst bed.
