Abstract

The MgAlFe mixed oxides derived from hydrotalcite-like compounds was impregnated with copper and tested for SO₂ removal under conditions similar to those of FCC units. By XRD, TG-DTG, BET and IR analysis, the sulfur transfer catalysts with 0.5-3.0% copper exhibited a better dispersion of copper in the precursor. The results of SO₂ adsorption-reduction test showed that the novel Cu/MgAlFe catalysts with 0.5-5.0% copper oxide achieved high oxidative adsorption rate and sulfur absorptive capacity, and did not affect the rate of reductive reaction and reducibility.
