Abstract: Processes for removing arsenic compounds from a feed stream using an adsorbent in disclosed. The process includes contacting a feed stream comprising at least arsenic and sulfur compounds with an adsorbent comprising an low-crystallinity manganese oxide, at least one halide and a binder, to provide a treated effluent substantially free of the arsenic and sulfur compounds.

Abstract: The invention provides a bound sulfided metal containing metals such as nickel, cobalt, iron manganese or zinc for removing selenocyanate from aqueous streams. The binder may be alumina, silica, clay or metal oxide. The amount of sulfur in the bound sulfided metal may range from 5-75% by weight. In one embodiment, the bound sulfided metal is formed and reduced and placed in a column system that comprises one or more columns and may comprise a Lead-Lag1-Lag2-Polisher series of columns.

Abstract: A process is provided for removing contaminants from olefin containing C4 streams. The streams are contacted with an X based zeolite adsorbent comprising greater than 88% X zeolite at a SiO2/Al2O3 ratio of less than 2.5 and an alkali metal salt present in excess of an amount required to achieve full exchange of cation sites on the X based zeolite. The resulting alkali oxide on a volatile free basis is less than 1% (by mass) of the X based adsorbent. The contaminants that are removed include sulfur, oxygenate, and nitrogen based contaminants.
