Concentrated on limestone-sulfur dioxide (SO2) reactions, alkaline additives research has defined the kinetics and capacity as well as the effects of overburning. The kinetics of SO2 sorption by limestone calcines has been determined with a high temperature differential bed gas solids contactor. The effects of particle size, percent conversion of CaO, sulfate loading, pore size, surface area, and geological type of carbonate rock were investigated. The loss of reactivity due to overburning was studied using an oil fired boiler belonging to a power company. Eighty-six carbonate rock samples were tested in a fixed-bed reactor to determine their capacity to react with flue gas containing sulfur dioxide. Although most of the work was performed with the carbonate and the oxide at standard test conditions, supplementary tests were made on hydrates, oxides and carbonates over a wide range of reaction temperatures and calcination conditions.
