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.
