As part of an investigation of the fluidised-bed combustion of coal and its environmental aspects, a study of the sorption of SO/sub 2/ as a combustion product has been undertaken. Special attention is being paid to the reactivation of fluidised-bed ash by treatment with water or water vapour, followed by heating to fluidised-bed temperatures. A laboratory research programme was carried out on the sulphation and reactivation of sorbents on their own, and of sorbent-containing ashes from a 4MW atmospheric fluidized-bed combustor. The experiments show that reactivation can be a versatile method for improving the efficiency of the sorbents.
