Abstract
A MCM-41 sorbent containing two metal oxides (CuO, CeO2) and an alkaline additive (LiCl) was prepared to remove SO2 from gas streams at 673K. Two impregnation methods i.e. the template-ion exchange and the two solvents impregnation method were employed yielding a high dispersed state of the metal oxides inside the porosity of the MCM-41 sorbent. The MCM-41 sorbent was found to have a high adsorption capacity of 130mg SO2/g at 673K. During the adsorption process, cerium oxide partially oxidized SO2 into SO3 which was further chemically adsorbed on active sites (CuO, Li2O). The formation of CuSO4 and Li2SO4 was observed by X-ray diffraction after the reaction.
