Aromatic and naphthenic solvents based on ethanol

A method for the preparation of hydrocarbon cuts, said method comprising:

• a) providing a hydrocarbon feedstock originating from ethanol 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 at step a) in order to obtain a hydrogenated hydrocarbon feedstock;
• c) a distillation step (i) of the hydrocarbon feedstock originating from ethanol of step a) or (ii) of the hydrogenated hydrocarbon feedstock of 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,
• the hydrocarbon feedstock of step a) having an initial boiling point and a final boiling point in the range going from 20 to 250° C.

A hydrocarbon cut having a difference of less than 100° C. between the final boiling point and the initial boiling point, said hydrocarbon cut comprising:

• a) a biocarbon content greater than or equal to 90% by weight with respect to the total weight of carbon atoms,
• b) a naphthenes and aromatics content selected from:
• b1) a naphthene content ranging from 2 to 20% by weight and a content of aromatics ranging from 30 to 60% by weight, with respect to the total weight of the hydrocarbon cut or
• b2) a naphthene content of 40 to 80% by weight and a content of aromatics of 500 ppm by weight or less, with respect to the total weight of the hydrocarbon cut,
• c) a content of non-cyclic paraffins ranging from 20 to 60% by weight.
