Abstract
In this work, the removal of SO 2 and NO from simulated flue gas from combustion process was investigated in a fixed-bed reactor using rice husk ash (RHA)/CaO-based sorbent. Various metal precursors were used in order to select the best metal impregnated over RHA/CaO sorbents. The results showed that RHA/CaO sorbents impregnated with CeO 2 had the highest sorption capacity among other impregnated metal oxides for the simultaneous removal of SO 2 and NO. Infrared spectroscopic results indicated the formation of both sulfate (SO 4 2−) and nitrate (NO 3 −) species due to the catalytic role played by CeO 2. Apart from that, the catalytic activity of the RHA/CaO/CeO 2 sorbent was found to be closely related to its physical properties (specific surface area, total pore volume and average pore diameter).
