Abstract
A process for removing sulfur oxides from a gas by contacting the gas with an acceptor comprising a lithium doped mixture of magnesium and aluminum oxides. The acceptor reacts with and retains the sulfur oxides. The retained sulfur oxides are then removed from the acceptor by reducing the acceptor through contact with hydrogen. The above process has the advantage of extremely high selectivity for hydrogen sulfide with regard to the effluent produced during the reduction step.
