Properties of a dolomite bed of a range of particle

A process for regenerating spent SO/sub 2/ sorbents has been developed on a PDU scale. Tymochtee dolomite that had been sulfated during fluidized-bed combustion of coal is regenerated (reductive decomposition of CaSO/sub 4/ to CaO and SO/sub 2/) by the incomplete combustion of either methane or coal in a fluidized-bed reactor.
