Layered double hydroxide sorbents for the removal of SO sub x from flue gas resulting from coal combustion

Patent ·
OSTI ID:7205360
; ;

This patent describes a process for removing SO{sub x} components from air in a flue gas stream containing oxygen, sulfur dioxide and sulfur trioxide from the combustion of coal within a coal fired boiler. It comprises combusting the coal in the boiler to provide the flue gas stream and contacting the the flue gas stream with a heated sorbent composition at a temperature between about 400{degrees} and 1000{degrees} C.
