Abstract
Publisher Summary This chapter discusses the kinetic study on low temperature and dry flue gas desulfursulfursulfurization. The thermobalance experiments observes the reaction kinetics under differential conditions by recording the weight change during the reaction of calcium oxide (Ca(OH) 2 ) with sulfur dioxide (SO 2 ). The low sample weights between 3 and 17 mg are used, and the reaction conditions are not differential during the first ten seconds. To distinguish between the weight gain by water adsorption and the weight gain by the SO 2 -reaction, the samples are first exposed to a H 2 O/N 2 /air mixture with the same humidity as the flue gas. Part of the N 2 is replaced by CO 2 and SO 2 to form synthetic flue gas. The investigated parameters are humidity, temperature, SO 2 -concentration, and the presence of carbon dioxide (CO 2 ).
