Title
MgAlFeCu mixed oxides for SO2 removal capacity: Influence of the copper and aluminum incorporation method
Abstract

MgAlFeCu mixed oxides derived from hydrotalcite-like compounds (Mg:Al = 5:1) in which Mg and Al were partially replaced by 1%(wt) Cu and 8%(wt) Fe. The mixed oxides were prepared by the impregnation method, the coprecipitation method and the novel NaAlO2-coprecipitation method, respectively. These additives were evaluated by SO2 removal under the conditions similar to those of FCC units. The results of SO2 adsorption–reduction test showed that MgAlFeCu-2 by the novel NaAlO2-coprecipitation method exhibited better adsorption capacities and reduction ability than other catalysts, its total amount of adsorbed SO2 reached 1.69 g SO2/g Cat, which also remained constant after 8 cycles.
