A cyclic process for the removal of hydrogen sulfide, and carbon dioxide, from a variety of gas streams is disclosed. The gas stream containing the sour gases is contacted with an aqueous solution of specific reactant materials, optionally in an absorbent, containing specific dialcohols for reaction rate improvement. The hydrogen sulfide is converted to sulfur, CO2 may be absorbed to produce a purified gas stream, and the reactant material is reduced. The process includes sulfur removal and regeneration of the reactant.
