Title:
METHOD FOR DESULFURIZATION OF HYDROCARBON OIL
Document Type and Number:
WIPO Patent Application WO/2007/015391
Kind Code:
A1
Abstract:
Disclosed is a method for desulfurization of a hydrocarbon oil (e.g., coal oil which is a raw fuel for a fuel cell) which can effectively remove a benzothiophene and a dibenzothiophene contained in the hydrocarbon oil under mild conditions to produce a desulfurized hydrocarbon oil having a significantly low sulfur content. The method comprises the step of desulfurizing the hydrocarbon oil with the combination of a solid acid-type desulfurizing agent and an active carbon-type desulfurizing agent. This method can provide a hydrocarbon oil having a significantly low sulfur content. By using the hydrocarbon oil, the operation or maintenance of a fuel cell system can be made easily, a fuel cell itself can be miniaturized in size, and the lifetime of a desulfurizing agent in a desulfurization apparatus equipped in a fuel cell system can be prolonged.
