Title:
METHOD FOR DESULFURIZATION OF LIQUID OIL CONTAINING ORGANIC SULFUR COMPOUND
Document Type and Number:
Japanese Patent JP2002322482
Kind Code:
A
Abstract:

To provide a method for desulfurization of a liquid oil containing organic sulfur compounds, with which sulfur in the liquid oil can be efficiently removed to ≤1 ppm sulfur content, and a first adsorbent (first desulfurizing agent) and a second desulfurizing agent have a long life, and a method for producing hydrogen for a fuel cell from the desulfurized liquid oil by a partial oxidation reforming treatment, an autothermal reforming treatment or a steam reforming treatment.

This method for desulfurization of a liquid oil containing an organic sulfur compound comprises treating the liquid oil containing the organic sulfur compound with an oxidizing agent, bringing the treated liquid oil into contact with the first and then the second desulfurizing agents. This method for producing hydrogen for a fuel cell comprises desulfurizing the liquid oil containing the organic sulfur compound and bringing the desulfurized liquid oil into contact with a partial reforming catalyst, an autothermal reforming catalyst or a steam reforming catalyst.
