Zeolite desulfurizing agent and carbon dioxide gas treatment application (ZEOLITIC DESULFURATION AGENTS AND THEIR APPLICATION TO CARBON DIOXIDE-CONTAINING GAS TREATMENT)

摘要

Treating the gas with an adsorbent made up of very small crystals of a partial Kalck zeolite A agglomerated by a low iron clay with reduced acidity and basicity to limit the production of carbon oxysulfide to very low levels, The gas having carbon can be desulfurized. Such clays can be obtained by the phosphorylation of montmorillonite, bentonite, ettpurite or kaolin.
