초록

There is provided a method and apparatus for treatment of a hydrogen-rich gas to reduce the carbon monoxide content thereof by reacting the carbon monoxide in the gas with an amount of oxygen sufficient to oxidize at least a portion of the carbon monoxide in the presence of a catalyst in a desired temperature range without substantial reaction of hydrogen. The catalyst is an iridium-based catalyst dispersed on, and supported on, a carrier. In the presence of the catalyst, carbon monoxide in a hydrogen-rich feed gas is selectively oxidized such that a pro...

청구항

[ What is claimed is:] [1.] A method of treating a feed gas comprising carbon monoxide and hydrogen, which comprises:reacting the carbon monoxide in the feed gas with an amount of oxygen sufficient to oxidize at least a portion of the carbon monoxide in the presence of an iridium catalyst dispersed on a refractory carrier such that a product gas is produced with a volumetric content of carbon monoxide that is less than that of the feed gas; and wherein a portion of the iridium is in a metallic state and a portion of the iridium is in a valence state high...
