Oil shale--SO/sub 2/ reactivity, determined with a thermogravimetric analyzer, was used to estimate the quantity of oil shale required to reduce SO/sub 2/ concentration in the effluent gas sufficiently to meet the SO/sub 2/ emission standard in atmospheric-pressure fluidized-bed coal combustion (AFBC). It was calculated that the oil shale could reduce the SO/sub 2/ concentration in the effluent gas from FBC units below the SO/sub 2/ emission limit. In evaluating virgin oil shale and spent oil shale for SO/sub 2/ emission control, we compared them with (1) Germany Valley limestone, (2) Greer limestone, and (3) Tymochtee dolomite. The results indicate that, due to the low calcium content of the shale, less dolomite or limestone than oil shale, may be required to meet the SO/sub 2/ emission standard. The attrition rate of Green River oil shale was found to be similar to attrition rates of limestones and dolomites.
