Abstract

Process for the production of a hydrocarbon fraction with a high octane number and a low sulfur content from a hydrocarbon feedstock, comprising at least the following stages: A hydrodesulfurization stage of the hydrocarbon feedstock, At least one stage for extracting aromatic compounds on all or part of the effluent that is obtained from the hydrodesulfurization stage, whereby said extraction leads to a paraffin-enriched raffinate and an aromatic compound-enriched extract sent to a gasoline pool to improve its octane number. A portion of the paraffinic raffinate can be used in a mixture with the aromatic extract; another portion can be used as a petrochemistry base either for producing aromatic compounds or for producing olefins.

Description

technical field

[0001] The present invention relates to the field of octane improvement of hydrocarbon fractions and further relates to a process for the production of high octane and low sulfur content hydrocarbon fractions which enables the upgrading of the entire fraction so that the fraction The total sulfur content of the fraction is reduced to very low levels while increasing the octane number of the fraction. Background technique

[0002] Oil refining and petrochemicals are now subject to new restrictions. Virtually all countries are gradually adopting strict sulfur regulations: the target is to reach 5 to 10 ppm sulfur. The problem of reducing the sulfur content is essentially centered on the gasoline obtained by cracking the main sulfur-containing precursors in the gasoline pool, whether the cracking is catalytic (FCC: Fluid Catalytic Cracking according to the English terminology) or non-catalytic (coking, visbreaking, steam-cracking). Today, there are plans to m...
