Abstract
In a reactor housing for conducting the catalytic oxidation of gaseous sulfur compounds, a plurality of empty tubes are arranged in an outer zone of the housing for having incoming gas to be reacted flow therethrough. Larger catalyst-filled tubes are arranged in an intermediate zone for having the gas flow therethrough after flowing through the empty tubes for performing the catalytic oxidation in the larger catalyst-filled tubes. An inner chamber includes an axial-flow pump arranged therein and is in communication with the outer and intermediate zones in such a way that a heat-transfer agent is caused to flow cross-currently into and out of the outer zone, intermediate zone and inner chamber for contacting the empty tubes and catalyst-filled tubes.
