THE SO2 REMOVAL AND REGENERATION PROPERTIES OF CeFeMgO SORBENT IN RFCC
IntroductionSulfur dioxide (SO2) is emitted form the many industrial processes that used the sulfur-containing compounds like fossil fuel. In Residue Fluid Catalytic Cracking (RFCC) and Fluid Catalytic Cracking (FCC) units, about 45%~55% of the sulfur in the hydrocarbon feedstock is converted to hydrogen sulfide in the reactor units and about 35%~45% remains in a liquid product. The rest 5%~10% of the sulfur is deposited on the FCC catalyst1. The Sox emissions 90% of SO2 and 10% of SO3 were usually produced form the regeneration units and they should be removed before their emission toward atmosphere in order to prevent environmental contamination2. In order to reduce it emissions, one or more metal oxide capable of Sox added cracking catalyst.(1~10wt%).
