Abstract: Metal exchanged and impregnated zeolite materials, methods for making metal exchanged and impregnated zeolite materials, and systems for reducing an amount of a contaminant species in a feed stream using a metal exchanged and impregnated zeolite material are provided. An exemplary metal exchanged and impregnated zeolite material comprises a metal exchanged zeolite material with the formula ((M2/nO)a.(M?2/n?O)a?). Al2O3.bSiO2; and a metal oxide with the formula M2/nO impregnated in the metal exchanged zeolite material such that the metal oxide is contacting an interior surface of the pore structure of the metal exchange zeolite material. In this example, M is a cation of an alkali or alkaline earth metal, n is a valence state of metal cation M, M? is a cation of a metal other than an alkali or alkaline earth metal, n? is a valence state of metal cation M?, 0 ?a<1, 0<a??1, a+a?=1, and b is about 2 to about 500.

Abstract: A method of removing mercury and/or sulfur from a fluid stream comprising contacting the fluid stream with a sorbent comprising a core and a porous shell formed to include a plurality of pores extending therethrough and communicating with the core. The core comprises a copper compound selected from the group consisting of a basic copper oxysalt, a copper oxide, and a copper sulfide.

Abstract: A method of removing heterocyclic sulfide impurities from a fluid stream is presented. The method comprises contacting the fluid stream with a sorbent comprising metallic copper.

Abstract: A method of removing O2, CO, H2, mercury, and/or sulfur from a fluid stream using a sorbent comprising metallic copper. The metallic copper is formed from direct reduction of a supported copper oxysalt by exposure to a reducing agent at a temperature of between about 40° C. and about 220° C.

Abstract: A method of removing H2S, a mercaptan, and/or COS from a fluid stream is presented. The method comprises contacting the fluid stream with a sorbent comprising Cu2O.
