PROCESS FOR PRODUCING HYDROREFINED GAS OIL, HYDROREFIND GAS OIL, AND GAS OIL COMPOSITION

摘要

A process of the present invention for producing a hydrotreated gas oil has a step for obtaining a product oil having a total aromatic content of 3% by volume or less by hydrogenating a hydrotreated oil including 95% by volume or more of fraction having a boiling point range of 150 - 380°C, a sulfur content of 2 - 15 ppm by mass, a total aromatic content of 10 - 25% by volume, and a naphthene of 20 - 60% by volume in the presence of a hydrogenation catalyst; and a step for obtaining, by hydrogenating the above-described product oil in the presence of a hydrogenation catalyst containing a crystalline molecular sieve component, a product oil satisfying the conditions that the content of petroleum fraction having a boiling point range of lower than 150°C is 16% by volume or less, and the sum of the total aromatic content and the total naphthene content is 80% or less relative to the sum of these in the hydrotreated oil.
