摘要： A manufacturing process of a diesel gas oil with a high cetane number and a low sulfur, where the cetane number thereof is at least 45, the sulfur content thereof is less than 350 ppm, and the storage stability is superior, from a petroleum distillate oil with a low cetane number and a high sulfur content is provided. The process includes a first stage of contacting hydrogen with a petroleum distillate oil with a particular low cetane number, a particular high sulfur content, and a particular boiling point, in the presence of a catalyst of a porous solid acid carrier carrying a particular hydrogenation-active metals at a particular temperature and pressure to obtain a hydrogenated oil with a cetane number of at least 45 and a sulfur content of less than 350 ppm; and a second stage of contacting the obtained hydrogenated oil with hydrogen in the presence of a catalyst of a porous carrier carrying a hydrogenation-active metal at a particular temperature and pressure to obtain a hydrogenated oil with a superior storage stability without changing the cetane number and the sulfur content.
