Layered Double Hydroxide Sorbents for the Removal of SO.sub.x from Flue Gas Resulting from Coal Combustion

Number: 5,116,587
Year: 1992
Patent Status: Issued
Authors: Pinnavaia, T.J., J. Amarasekera, C.A. Polansky

Processes for removing noxious oxides from gas streams, particularly from flue gases of coal-burning power plants, using heated layered double hydroxide (LDH) sorbents are described. The sorbent compositions contain metal components, incorporated into the sorbents either by isomorphous replacement of all or part of M.sup.II and /or M.sup.III ions in layers of LDH structures or by impregnation as a metal salt, to promote the oxidation of sulfur dioxide.
