Process for the desulfurization of flue gas
Patent
·
OSTI ID:7198643
A process is described for the removal of sulfur oxides from a gas, which comprises the steps of contacting the gas with a cerium oxide sorbent at a temperature of from 300/sup 0/ to 800/sup 0/C until the cerium oxide sorbs sulfur oxide, and regenerating the spent sorbent by contacting with hydrogen wherein during regeneration the sulfur sorbed cerium is subsequently converted to cerium oxide and the desorbed sulfur specie is initially sulfur dioxide and subsequently hydrogen sulfide.
