The invention concerns a petroleum product and a process for the production of a petroleum product which can form part of a blend for an internal combustion engine fuel, the process comprising a) hydrotreating a hydrocarbon feedstock at a partial pressure of hydrogen at the reactor outlet of about 0.5 MPa to about 6 MPa, b) separating a product (P) from step a) into a product (P1) with a final boiling point of about 300.degree. C. and a product (P2) with an initial boiling point greater than the final boiling point of product (P1), c) performing a liquid-liquid extraction with a solvent (S1), to produce an extract (E1) and a raffinate (R1) from product (P2), d) recovering solvent (S1) from raffinate (R1) to produce a product (Q1), depleted in solvent (S1), which has improved qualities and contains less than 500 ppm by weight of sulphur.

A fuel for internal combustion engines having an improved cetane index and lower sulfur content is obtained from a hydrocarbon charge, by a process comprising a step (a) for distillation (D1) in which a bottom product (Q1) is obtained via a line 3 and in which a top product (T1) is obtained via a line 2, a step (b) of liquid/liquid extraction (LE) using a solvent (S1) to obtain a raffinate (R1), (line 5) an extract from which product (Q1) is obtained (line 6), a step c) separating (D2) the raffinate (R1) enabling a product (Q2) to be obtained via line 7, which product has a low solvent (S1) content, and a step (d) of hydrotreatment (HDS) in which the mixture of the products (T1) and (Q2) are subjected to hydrotreatment with a hydrogen partial pressure of less than 10 megapascals, to obtain a product (P) (line 9) which has improved qualities and which contains less than 500 ppm by weight sulphur. According to one particular embodiment, the extract (E1) (line 6) is distilled in order to obtain, via line 11, a bottom product (Q3) which is then conveyed to a hydrotreatment zone in such a way that a product (P') is obtained via a line 12 which contains less than 0.3% by weight sulphur.
