    Abstract: Device and process for converting a feedstock of aromatic compounds, in which the feedstock is notably treated using a fractionation train (4-7), a xylenes separating unit (10) and an isomerization unit (11), and in which a pyrolysis unit (13) treats a second hydrocarbon-based feedstock, produces a pyrolysis effluent feeding the feedstock, and produces a pyrolysis gas comprising CO, CO2 and H2; an RWGS reverse water gas shift reaction section (51) treats the pyrolysis gas and produces an RWGS gas enriched in CO and in water; a fermentation reaction section (52) treats the RWGS gas enriched in CO and in water and produces ethanol; and an aromatization reaction section (14) converts the ethanol into a mixture of aromatic and paraffinic compounds feeding the feedstock.

    Abstract: The invention concerns a method for converting heavy hydrocarbon feedstocks of which at least 50% by weight boils at a temperature of at least 300° C., and in particular vacuum residues. The feedstocks are subjected to a first step a) of deep hydroconversion, optionally followed by a step b) of separating a light fraction, and a heavy residual fraction is obtained from step b) of which at least 80% by weight has a boiling temperature of at least 250° C. Said fraction from step b) or the effluent from step a) is then subjected to a second step c) of deep hydroconversion. The overall hourly space velocity for steps a) to c) is less than 0.1 h−1. The effluent from step c) is fractionated to separate a light fraction. The heavy fraction obtained, of which 80% by weight boils at a temperature of at least 300° C., is sent to a deasphalting step e). The deasphalted fraction DAO is then preferably converted in a step f) chosen from ebullated bed hydroconversion, fluidised bed catalytic cracking and fixed bed hydrocracking.

    Abstract: A process for producing BTX and alcohols from biomass, comprising at least a) catalytic pyrolysis of said biomass in a fluidized-bed reactor producing a gaseous pyrolysis effluent; b) separation of said gaseous pyrolysis effluent into at least one BTX fraction and a gaseous effluent comprising at least carbon monoxide and carbon dioxide, c) recycling at least part of said gaseous effluent comprising at least carbon monoxide and carbon dioxide into the reactor of said step a), d) purging said gaseous effluent recycled according to step c) to produce a purge effluent, e) sending at least part of said purge effluent from step d) into a fermentation step producing a liquid fermentation stream comprising at least one stream comprising at least one oxygenated compound chosen from alcohols, diols, acid alcohols, carboxylic acids, aldehydes, ketones and esters, alone or as a mixture.
