A process is disclosed for regenerating spent MgO-vermiculite and MgO-perlite sorbents, where the sorbents have been employed beforehand to remove sulfur and nitrogen oxides from flue gases. The regeneration process consists of a series of heating and cooling steps performed in controlled atmospheres during which time sulfur oxides and elemental sulfur are recovered, nitrogen oxides are destroyed, and the sorbents are returned substantially to their original condition.
