Abstract: A catalyst that oxidizes carbon monoxide includes a bimetal consisting of platinum and a transition metal in a bimetallic phase that is loaded on γ-alumina support. The catalyst is manufactured by uniformly mixing a platinum precursor, a transition metal precursor, and γ-alumina (γ-Al2O3) in a dispersion medium to provide a mixture; drying the mixture; calcining the dried mixture; and reducing the calcined dried mixture. Since the catalyst that oxidizes carbon monoxide has high reaction activity even at low temperature and excellent reaction selectivity, and a methanation reaction and reoxidization do not occur, and the catalyst can effectively eliminate carbon monoxide in the fuel.

Abstract: A desulfurizer for fuel gas for a fuel cell includes: a first adsorption tank including an adsorber having selective adsorption capacity for a thiophene-based compound and a second adsorption tank including an adsorber having selective adsorption capacity for a mercaptan-based compound. The desulfurizer uses separate adsorbers having selective adsorption capacity for a thiophene-based compound and a mercaptan-based compound, in multiple stages to perform a more efficient and economical desulfurizing of a fuel gas to remove various sulfur compounds, especially thiophene-based compounds and mercaptan-based compounds compared to a desulfurizer using a single adsorber.
