摘要： A process for obtaining a fuel for internal combustion engines from a hydrocarbon charge, 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 to (R1), (line 5) and an extract from which product (Q1) an extract (E1) is obtained (line 6) and a raffinate, a step c) of 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.
