  • Zeolite adsorbents, method for obtaining them and their use for removing carbonates from a gas stream
    Patent number: 6616732
    Abstract: The present invention relates to a novel family of zeolite adsorbents comprising a mixture of zeolite X and zeolite LSX, these adsorbents being predominantly exchanged with sodium or with strontium. These adsorbents are particularly suited to the decarbonatation of gas flows contaminated by CO2.

  • Zeolitic desulfuring agents and their application in the processing of gasses containing notable CO.sub.2 proportions
    Patent number: 5609842
    Abstract: It 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.
