Reactor for the catalytic conversion of H2S and SO2 present in a gas stream into elemental sulphur

摘要

There is described a reactor having a catalyst bed for the catalytic conversion of H2S and SO2 present in a gas stream into elemental sulphur. To achieve, when operating the reactor below the dew point of sulphur or the solidification point of sulphur, as high a uniformity as possible in the cooling or heating of the catalyst charge in the case of adsorption or regeneration, the reactor is at least partially cooled or heated internally and at least one cooling/heating coil is arranged in at least one part of the catalyst bed. It is here also provided that the catalyst bed is divided into a number of sub-beds which contain different catalysts.
