Provided is a process and catalyst for hydrocracking paraffinic hydrocarbons which provides satisfactorily high cracking activity and middle distillate yield as well as the low pour point of the resulting gas oil all together. The catalyst of the present invention comprises a crystalline aluminosilicate, alumina-boria and a noble metal of Group VIII of the Periodic Table.

Process for producing liquid hydrocarbon with hydrocracking catalyst

A catalyst is provided which is low in methane selectivity in a high CO conversion region and high in chain growth probability &#x3b1; in a Fischer-Tropsch synthesis and comprises a support comprising silica or alumina and an oxide of zirconium and/or titanium loaded thereon in film form in an amount ranging from 0.5 percent by mass to 10.0 percent in terms of metal, and one or more metals selected from the group consisting of cobalt, nickel and ruthenium loaded on the support.

Catalyst for Fischer-Tropsch synthesis and process for producing hydrocarbons

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.

Manufacturing process of diesel gas oil with high cetane number and low sulfur

There is provided a method of manufacturing gas oil containing low-sulfur and low-aromatic-compound content, said method including a first step of putting distilled petroleum to contact with hydrogen gas in the presence of a hydrotreating catalyst to reduce the sulfur concentration to not higher than 0.05 wt % and a second step of reducing the aromatic compound concentration in the presence of a noble metal type catalyst, with at least a pair of high temperature high pressure gas liquid separators arranged between the two steps to separate the gaseous and liquid components of distilled petroleum and hydrogen gas or hydrogen containing gas is introduced into the liquid component in each of the separators.
