Fuel oil for use both in internal combustion in engine and fuel cell

Abstract

A fuel oil for use both in an internal combustion engine and in a fuel cell containing 50% by volume or more of an alkylate gasoline, and, optionally, 1 to 50% by volume of isopentane, 1 to 12% by volume of a hydrocarbon having 4 carbon atoms, 7% by volume or less of an oxygen-containing compound, and 1 to 30% by volume of a desulfurized light naphtha; and a fuel oil for use both in an internal combustion engine and in a fuel cell containing 10 to 60% by volume of a desulfurized light naphtha, 40 to 90% by volume of a benzene-free reformed gasoline and 0 to 10% by volume of a hydrocarbon having 4 carbon atoms. Each of the above fuel oils is a fuel oil for a fuel cell which can produce hydrogen with good efficiency, has no adverse effect on reforming catalysts and electrodes for a fuel cell, and is reduced in deactivation of reforming catalysts and the like, and a fuel oil for an internal combustion engine which has a high octane number and can be used without causing knocking or the like.
