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.
