PCT No. PCT/FR94/00932 Sec. 371 Date Nov. 22, 1994 Sec. 102(e) Date Nov. 22, 1994 PCT Filed Jul. 26, 1994 PCT Pub. No. WO96/03199 PCT Pub. Date Feb. 8, 1996It is now possible to desulfurize gases containing appreciable carbon dioxide proportions by limiting the production of carbon oxysulfide to a very low level, by treating these gases with adsorbents composed of very small, partially calcic zeolite A crystals agglomerated by clays containing low levels of iron and having reduced acidity and basicity. These clays may be obtained by phosphatization of montmorillonite, bentonite, attapulgite, or kaolin.
