A development program on pressurized fluidized-bed combustion is being carried out in a bench-scale pilot plant capable of operating at 10-atm pressure. The concept involves burning fuels such as coal in a fluidized bed of particulate lime additives that reacts with the sulfur compounds formed during combustion to reduce air pollution. Nitrogen oxide emissions are also reduced at the combustion temperatures used, which are lower than those used in a conventional coal combustor. The CaSO/sub 4/ produced in the combustor is regenerated to CaO that is recycled to the combustor for further removal of sulfur compounds. This report presents information on: a 10-cycle combustion-regeneration experiment, bench-scale regeneration experiments, regeneration kinetics, preparation of synthetic SO/sub 2/-sorbents containing metal oxides, sorbent attrition, coal combustion reactions, and studies of the enhancement of the sulfation rate of limestone by NaCl.
