Abstract
A desulfurization apparatus according to the present invention includes: a first desulfurizer filled with a first desulfurization agent that removes a first sulfur compound from a hydrocarbon fuel; and a second desulfurizer filled with a second desulfurization agent that removes a second sulfur compound from the hydrocarbon fuel, the second desulfurizer being provided downstream of the first desulfurizer in a flow direction of the hydrocarbon fuel. The second desulfurization agent is constituted by a porous coordination polymer having a polymeric structure that is a combination of copper ions and organic ligands. A sulfur compound adsorption ability of the second desulfurization agent to adsorb the second sulfur compound is different from a sulfur compound adsorption ability of the first desulfurization agent to adsorb the first sulfur compound. A temperature of the second desulfurization agent is kept to 100° C. or lower. The desulfurization apparatus thus configured makes it possible to efficiently remove the sulfur compounds from the hydrocarbon fuel at low cost with a simple configuration.
