Abstract
Decrepitation of the catalyst occurring in the initial upstream portion of the catalyst bed of the reaction zone in a process for catalytically reducing sulfur dioxide to obtain elemental sulfur is avoided or minimized by employing as the catalyst in at least the initial upstream portion of the bed a supported sulfate of an iron group metal.
