    • Process for the preparation of a middle distillate having good properties at low temperatures, which can be used as fuel, starting from a mixture of substantially linear hidrocarbons, without sulfur and containing at least 20% of a high-boiling fraction having a distillation temperature exceeding 370° C., comprising, as single reactive step, a “hydrocracking” step on said mixture of linear hydrocarbons, at a temperature ranging from 250 to 450° C. and a total pressure of 0.5 to 15 MPa, in the presence of a supported catalyst comprising: (A) a carrier of an acid nature consisting of a calcined gel of silica-alumina amorphous to X-rays having a molar ratio between silica and alumina within the range of 30 and 500, a surface area within the range of 500 and 1000 m2/g, with a porosity within the range of 0.2 and 0.8 ml/g, with an average pore diameter ranging from 10 to 40·10−10 m (from 10 to 40 Å); (B) one or more noble metals of groups 8, 9 or 10 of the periodic table of elements, arranged on said carrier (A) in a quantity ranging from 0.05 to 5.0% by weight.
