Abstract
The kinetics of the reaction of limestone/dolomite with H2S have been examined under fuel rich combustion conditions. The experiments were done in a tubular laminar flow reactor with co-current flow of gas and solids. In the temperature region, 1065-1310°C, the results were consistent with the absorption reaction of H2S first order with respect to calcium and half order with respect to H2S. Reactivity of the stones fell off substantially between 1065-1310°C because of severe desurfacing occurring at these temperatures to the limestone and dolomite. A diffusion controlled reaction is believed to be the dominant mechanism.Keywords
