Abstract: The invention relates to a preparation method for hydrocarbon cuts, said method comprising: a) providing a hydrocarbon feedstock originating from ethanol having an initial boiling point and a final boiling point in the range from 20 to 250° C. and comprising: from 20 to 60% by weight of aromatic compounds; from 20 to 60% by weight of non-cyclic paraffins; and from 2 to 20% by weight of naphthenes, with respect to the total weight of the hydrocarbon feedstock, b) optionally, a step of hydrogenation of the hydrocarbon feedstock originating from ethanol provided during step a) in order to obtain a hydrogenated hydrocarbon feedstock; c) a distillation step (i) of the hydrocarbon feedstock originating from ethanol during step a) or (ii) of the hydrogenated hydrocarbon feedstock according to step b), in order to obtain at least one hydrocarbon cut having a difference of less than 100° C. between the final boiling point thereof and the initial boiling point thereof.

Abstract: The invention is a process for dearomatization and isomerization of a feedstock having less than or equal to 10 ppm by weight of sulphur, the process comprising:



Hydrodearomatizing the feedstock at a temperature ranging from 150 to 220° C. and at a pressure ranging from 20 to 150 bars, in order to provide a dearomatized product;
Hydroisomerizing the dearomatized product at a temperature ranging from 250 to 320° C. and at a pressure ranging from 40 to 60 bars in the presence of a catalyst based on platinum or palladium, in order to provide an isomerized product;
Hydrodearomatizing the isomerized product at a temperature ranging from 150 to 220° C. and at a pressure ranging from 20 to 150 bars, in order to provide an isomerized and dearomatized product.
