Process Using Sorbents for the Removal of SO.sub.x from Flue Gas

Number: 5,114,691
Year: 1992
Patent Status: Issued
Authors: Pinnavaia, T.J., J. Amarasekera, C.A. Polansky

A process of removing noxious sulfur oxides from gas streams using heated layered double hydroxide (LDH) sorbents is described. The sorbent compositions contain metal components incorporated into the galleries of the LDH structures in the form of metal-containing oxo-anions, to promote the oxidation of sulfur dioxide.
