Abstract: To provide a method for hydrotreating a synthetic hydrocarbon oil, which removes olefins and oxygen-containing compounds by hydrotreatment with the gasification rate restrained and can efficiently convert the synthetic hydrocarbon oil generated by the FT process to a liquid fuel suitable as a fuel for diesel-powered vehicles. A hydrotreating method is disclosed in which a synthetic hydrocarbon oil generated by FT synthesis is hydrotreated using a catalyst in which a definite catalytic metal is allowed to be carried on a support, under definite reaction conditions, with the gasification rate restrained to a definite value or less, thereby removing the olefins and the oxygen-containing compounds.

Abstract: To efficiently obtain a liquid fuel containing no sulfur and having good cold flow properties by hydrotreating heavy wax generated by the Fischer-Tropsch (FT) synthesis to perform cracking with the gasification rate restrained and also increase an isomerization reaction which occurs at the same time. A method for producing a hydrocarbon fuel oil, in which heavy wax generated by the FT synthesis is hydrotreated with a catalyst of the platinum group using zeolite or silica-alumina as a support under specific reaction conditions corresponding to the kind of the support, thereby performing cracking and an isomerization reaction.
