Method for removing SOX gas containing in FCC Unit comprising contacting the gas with SOX removing Additive, which is Free Will, The Additive comprises Absorbent with source of A1Divalent Component selected from mg and ca and ca

摘要

The sulfur oxide removing additive suitable for a FCC unit at low oxygen environment condition is described. The SOSUBx /SUBremoving 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 SOSUBx /SUBremoving additive at a low oxygen environment condition.
