Claim Text:
1. A method for manufacturing an aviation fuel oil base comprising: hydrotreating an oil, containing an oxygen-containing hydrocarbon compound, which is derived from an animal or vegetable oil and fat and a sulfur-containing hydrocarbon compound with a catalyst prepared by supporting at least one metal selected from the elements of groups 6A and 8 of the periodic table on a support formed of a porous inorganic oxide composed of two or more elements selected from aluminum, silicon, zirconium, boron, titanium, and magnesium, under conditions of a hydrogen pressure of 2 to 13 MPa, a liquid hourly space velocity of 0.1 to 3.0 h adding a recycled oil being a part of the resultant hydrotreated oil to the oil to be hydrotreated in an amount of 0.5 to 5 times by mass relative to the oxygen-containing hydrocarbon compound derived from an animal or vegetable oil and fat, and then hydroisomerizing the resultant hydrotreated oil with a catalyst prepared by supporting a metal selected from the elements of group 8 of the periodic table on a support formed of a porous inorganic oxide composed of a substance selected from aluminum, silicon, zirconium, boron, titanium, magnesium, and zeolite, under conditions of a hydrogen pressure of 1 to 5 MPa, a liquid hourly space velocity of 0.1 to 3.0 h
