H2S is removed from gases by absorption in a soln. contg. an alk. reagent and a metal phthalocyanine, and the satd. absorbent is regenerated by blowing air through it, forming elemental S. The regeneration rate is increased by carrying out the absorption in the presence of sol. salts of Mn(II) at a pH of 8.5-12. The Mn(II) salt is added to the soln. in an amt of 0.01-1 g/L, calcd. as Mn.
