Gas oils comprises one or more gas oil bases obtained by subjecting specific fractions from distilled petroleum fractions to hydrogenating treatment under specific conditions and optionally a small amount of a straight kerosene or gas oil. The gas oils have a sulfur concentration of 350 ppm or below.

Low sulfur gas oil

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.

An object is to increase cracking rate of heavy fraction oils while producing a lessened amount of dry gases generated by the hydrogen transfer reaction and by the overcracking to obtain light fraction olefins in a high yield. A process for the fluid catalytic cracking of heavy fraction oils, which comprises steps of feeding the heavy fraction oils to a raw oil introducing portion provided at a reaction zone inlet; feeding a part of a regenerated catalyst taken out of a catalyst-regenerating zone to a catalyst introducing portion provided at a reaction zone inlet; and feeding another part of the regenerated catalyst taken out of the catalyst-regenerating zone to at least one catalyst introducing portion which is provided between the catalyst introducing portion provided at the reaction zone inlet and reaction zone outlet, the catalytic cracking in the reaction zone being carried out under conditions of a contact time of 0.1 to 3.0 sec. a reaction zone outlet temperature of 530 to 700.degree. C. and a catalyst/oil ratio of 10 to 50 wt/wt, thereby producing light fraction olefins.
