A detailed study was undertaken to examine the potential of iron oxide present in red mud - a waste product from Bayer's alumina process - as a sorbent for SO2 capture by dry process. The other constitutents present in the red mud can bring about enhanced utilization of the active component provided they are almost completely inert. The practical use of the process has been explored and a few batchwise cyclic operations of SO2 capture and regeneration have also been carried out. A kinetic model of the reaction has been proposed.
