  • Patent number: 8702973
    Abstract: One exemplary embodiment can be a process for upgrading one or more hydrocarbons boiling in a naphtha range including less than about 5%, by weight, one or more alkenes and about 2,000-about 5,000 wppm, S, comprised in one or more sulfur-containing compounds, based on the weight of the one or more hydrocarbons. The process can include contacting the one or more hydrocarbons with a catalyst. The catalyst may include about 0.1-about 10%, by weight, NiO, about 5-about 50%, by weight, MoO3, and about 0.1-about 10%, by weight, P, with the balance of the catalyst comprising Al2O3. The process can obtain an upgraded one or more hydrocarbons having a thiol concentration of no more than about 20 wppm, S, based on the sulfur comprised in one or more thiol compounds divided by the weight of the upgraded one or more hydrocarbons.

  • Publication number: 20020117426
    Abstract: The present invention relates to a process for hydrodesulphurising a gas oil wherein a sulphur level of less than 50 ppm is obtained, said process comprising a) contacting a gas oil with hydrogen in the presence of a hydrodesulphurisation catalyst, and b) adjusting the temperature and pressure of hydrodesulphurisation so the temperature-pressure relationship lies on or between the curves T=211.15 P0.1363 and T=243.83 P0.1232, for all values of P≧0 where T=temperature in ° C., and P=pressure in bar a.
