Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for removing oxygen from an oxygen containing gas mixture comprising the steps of: providing a partially oxidized form of a metal carbonate selected from the group consisting of manganese carbonate, iron carbonate, nickel carbonate and cobalt carbonate, wherein said partially oxidized form of metal carbonate has a crystallite particle size of less than about 0.08 microns; contacting said partially oxidized form of metal carbonate with said gas mixture; and adsorbing said oxygen from the gas mixture without generating water to produce a purified gas. 2. The process of claim 1 wherein said adsorption is carried out at a temperature from about 20° C. to about 200° C. 3. The process of claim 1 wherein said gas mixture comprises from about 1 to about 100 ppm oxygen. 4. The process of claim 1 wherein said gas mixture further comprises hydrocarbons. 5. The process of claim 4 wherein said hydrocarbons comprise methane. 6. The process of claim 1 wherein said gas mixture further comprises hydrogen and carbon monoxide. 7. The process of claim 1 wherein said purified gas contains no more than about 0.1 ppm oxygen.
