  • Publication number: 20240326010
    Abstract: Adsorbent compositions are described. The adsorbent compositions include a metal oxide/mixed metal oxide component, a zeolite component, a metal carbonate component, and optionally a binder. The adsorbent compositions provide high inorganic and organic chloride capacity, controlled acidity, low polymerization/green oil formation, improved hydrothermal stability and mechanical properties including crush strength, increased adsorbent life, and fewer plugging byproduct-formation concerns. Methods of removing organic chlorides and inorganic chlorides from a process fluid using the adsorbent compositions are also described.
