Abstract

Abstract: MgAlCuFe obtained from hydrotalcite-like compounds showed excellent s ulfur transfer ability for SOx removal from FCC flue gas. In the catalysts , Cu1%Fe8%-LDOs (n(Mg)/n(Al)=5) exhibited total saturation adsorption capacity of 1.57 g/g in 6 min and high adsorption-redu ction rates under the conditions similar to those of a typical FCC.

Key words: sulfur transfer catalyst, hydrotalcite, complex metal oxide, sulfur oxidative adsorption, reductive desorption
