Estimating the term…
The present invention relates to a gas processing agent for removing carbon monoxide, hydrogen, carbon dioxide and water vapor in a gas at the same time, which can maintain a high oxidation activity and have a long life time, a manufacturing method therefor and a gas purification method. More specifically, the present invention relates to a gas processing agent made of a catalyst made of an inorganic porous material layer containing at least one selected from a group consisting of platinum, palladium, rhodium and ruthenium, or oxides thereof and an adsorbent, and a manufacturing method therefor, a gas purifier, a gas purification method and a gas purification apparatus using the gas processing agent.
A gas processing agent obtained by forming a catalyst layer which has a thickness of 10-500 μm and is made of an inorganic porous material containing at least one element selected from the group consisting of platinum, palladium, rhodium, ruthenium and oxides thereof, on a surface of an adsorbent, and the inorganic porous material containing at least one component selected from the group consisting of alumina, titania, silica, silica-alumina, zirconia and tin-oxide, and the adsorbent is at least one selected from the group consisting of Li-X, Na-X, Ca-X, Ba-X, Na-A and Ca-A type zeolite.
