1. A method for removing at least one of an arsenic compounds and sulfur compounds from a feed stream comprising contacting the feed stream with an adsorbent comprising a manganese oxide in an amount of about 20 to about 80 wt %, at least one halide in an amount of about 0.25 to about 1.5 wt % and a binder, to provide an effluent stream comprising less than about 20 wppb of the at least one of the arsenic compounds and sulfur compounds.
