  • Method for treating an organic liquid contaminated with an iodide compound
    Patent number: 5962735
    Abstract: A solution is provided to the long sought inorganic alternative to resin based adsorbents for iodide clean-up service for corrosive organic liquid. The solution involves the use of a solid inorganic adsorbent comprising a combination of a silica-rich zeolite molecular sieve, which has been cation-exchanged with an iodide-reactive metal selected from silver, mercury, copper, lead, thallium, palladium or mixtures thereof, with a substantially insoluble, porous refractory inorganic oxide binder. Reactivation and regeneration technique for the spent inorganic adsorbent are also covered.
