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.

The present invention relates to a process for producing benzene from a mixed hydrocarbon feedstream comprising subjecting C6 cut separated from said mixed hydrocarbon feedstream to aromatization to provide a benzene-rich aromatic stream and recovering the benzene from the benzene-rich aromatic stream.

Multiple catalytic processing stations couple with a system which produces volatile gas streams from biomass decomposition at discrete increasing temperatures. These catalytic processing stations can be programmed to maximize conversion of biomass to useful renewable fuel components based on input feedstock and desired outputs.
