Abstract:	Kinetics of So2 removal using a copper-based sorbent CuO/γ-Al2O3 and a cerium modified copper sorbent CuO-CeO2/γ-Al2O3 were measured on a TGA and their kinetics behaviors were simulated with a proposed empirical rate model (ERM). The purpose of cerium addition to the copper sorbent was to study the difference of sorbent's kinetics. The cerium modified copper sorbent showed a higher reaction rate on initial sulfation than the regular copper sorbent. Both sorbents however had similar calculated activation energy. The proposed ERM model appeared to describe the SO2 removal kinetics well in the temperature range 250-400 ºC.
