Process Using Recyclable Sorbents for the Removal of Sox from Flue Gases and Other Gas Streams

Number: 5,785,938
Year: 1998
Patent Status: Issued
Authors: Pinnavaia, T.J., M. Chibwe, J. Amarasekera

A process for removing and then capturing noxious sulfur oxides from gas streams, particularly from the flue gases of coal-burning power plants, using Ni-containing heated layered double hydroxide (LDH) as recyclable sorbents. The sorbent compositions contain metal components that form stable metal sulfites and sulfates at one temperature, but are decomposed at a higher temperature to regenerate the sorbent material.
