The method according to this disclosure is a method for separating an unsaturated hydrocarbon having 2 or 3 carbon atoms and a halogenated unsaturated carbon compound formed by replacing at least one of hydrogen atoms included in the unsaturated hydrocarbon with a fluorine atom, from each other and is a method for selectively adsorbing either the unsaturated hydrocarbon or the halogenated unsaturated carbon compound by a porous coordination polymer that includes a metallic ion having a valence of 2 to 4 and an aromatic anion having 1 to 6 aromatic ring(s).

A proton conductor includes a complex of phosphoric acid and a coordination polymer in which a metal ion and a ligand are continuously connected by a coordinate bond. The phosphoric acid includes a first phosphoric acid that is coordinately bonded to the metal ion, and a second phosphoric acid that is not coordinately bonded to the metal ion.

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&#xb0; 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.
