Abstract
A system is provided for desulfurizing a hydrocarbon fuel containing a light amount of methanol and a slight amount of water. The desulfurization system uses a Y-type zeolite-based desulfurizing agent containing at least copper arranged upstream of the system and an X-type zeolite-based desulfurizing agent containing at least silver arranged downstream of the system and thus can maintain desulfurization effect for a long period of time.
