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.

Enhancement of reduction resistance for manganese oxide adsorbents

An adsorption process is provided to remove oxygen from a hydrogen stream through the use of a copper material in combination with layers of adsorbent to remove water and nitrogen from a hydrogen stream. This process is particularly useful for purification of hydrogen product gas from water electrolyzers with the hydrogen product gas having greater than 99.9 mol % purity.

Process for removing oxygen from a hydrogen stream

A process is provided for removing contaminants from olefin containing Cstreams. The streams are contacted with an X based zeolite adsorbent comprising greater than 88% X zeolite at a SiO/AlOratio 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.

Adsorbent for contaminant removal from C4 hydrocarbons

The present subject matter relates generally to a method for the removal of oxygen from hydrogen using a manganese, iron, nickel or cobalt based adsorbent. More specifically, the present subject matter relates to the methods for the removal of oxygen from hydrogen using a manganese based adsorbent without the generation of water or other oxides.

Method for oxygen removal from hydrogen using adsorbent

A process is presented for the removal of acetaldehyde from mixture of oxygenates. Acetaldehyde is selectively removed in the presence of other oxygenates like ketones, alcohols and nitriles using an amorphous sodium doped alumina derived from thermally decomposed Dawsonite. The process successfully removes acetaldehyde which can adversely impact catalyst operation.

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 ((MO).(M'O)). AlO.bSiO; and a metal oxide with the formula MO 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&#x2032; is a cation of a metal other than an alkali or alkaline earth metal, n&#x2032; is a valence state of metal cation M&#x2032;, 0 &#x2266;a&#x3c;1, 0&#x3c;a&#x2032;&#x2266;1, a+a&#x2032;=1, and b is about 2 to about 500.

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.

Method for removal of heterocyclic sulfur using metallic copper

A method of separating a target component from a chemical mixture comprising contacting a chemical mixture with a microporous coordination polymer. The microporous polymer is described by the formula:[M(CHO)]where M is a transition metal, rare earth metal, or other element from the groups consisting of IIA through VB.
