METAL IMPREGNATED ZEOLITE ADSORBENTS, METHODS OF MAKING, AND SYSTEMS FOR USING THE SAME

摘要

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
