<p>The sulfur oxide removing additive suitable for a FCC unit at low oxygen environment condition is described. The SOx removing additive includes one or more sorbents and one or more oxidation catalysts. The sorbent includes a source of Al and a divalent component. The divalent component is selected from a group consisting of magnesium, calcium, and combinations of two or more. The oxidation catalyst includes a source of cerium. The SOx removing additive is substantially free of vanadium. Also described is a method of removing the sulfur oxide content of a sulfur oxide-containing gas from an FCC unit. The method includes contacting the gas with a SOx removing additive at a low oxygen environment condition.</p> |
