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.

Method for treating an organic liquid contaminated with an iodide

An improved process is disclosed for the isomerization of butenes, using a catalyst comprising a non-zeolitic molecular sieve to increase the proportion of isobutene or of 1-butene in the product with low formation of undesirable by-products.
