摘要
The present invention is directed to a process for removing SO2 from an SO2-containing gas stream by catalytically reducing the SO2 to elemental sulphur, in which process a gas stream comprising SO2 and a reductor chosen from H2, CO, and a mixture thereof, the molar ratio of the reductor to the SO2 being between 0,1 and 10, is contacted, at a temperature in the range of 180 DEG to 300 DEG C and a pressure of between 1 and 60 bar, with a sulphur resistant catalyst comprising at least one hydrogenation function. The catalyst preferably comprises a Group VIB metal component and/or a Group VIII metal component on a carrier. The process according to the invention can be used for removing SO2 from SO2-containing gas streams derived from various sources, int. al., from a modified SuperClaus unit. The process according to the invention permits the removal of SO2 from an SO2-containing gas stream in a simple manner with high SO2 conversion and a high selectivity for elemental sulphur.
