<p>An object of the present invention is to provide a desulfurizing and refining method for hydrocarbon oil for reducing sulfur compounds to an extremely low concentration at a relatively low equipment cost and operating cost. The method for desulfurizing hydrocarbon oils comprises causing a hydrocarbon oil containing at least one sulfur compound selected from the group consisting of thiophene compounds, benzothiophene compounds, and dibenzothiophene compounds or a hydrocarbon oil further containing aromatic hydrocarbons to come in contact with a solid acid catalyst and/or activated carbon containing a transition metal oxide. The solid acid catalyst is preferably a solid superacid catalyst selected from sulfated zirconia, sulfated alumina, sulfated tin oxide, sulfated iron oxide, tungstated zirconia, and tungstated tin oxide.</p> |
