Abstract
A process is described for producing BTX and alcohols from biomass, by a) catalytic pyrolysis of the 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 containing at least carbon monoxide and carbon dioxide, c) sending all of the gaseous effluent from separation b) into fermentation producing a liquid fermentation stream containing at least one stream containing at least one oxygenated compound chosen from alcohols, diols, acid alcohols, carboxylic acids, aldehydes, ketones and esters, d) separating the fermentation stream obtained on conclusion of c) into at least the stream containing at least one oxygenated compound, an aqueous fraction, and an unreacted gaseous effluent, e) recycling at least part of unreacted gaseous effluent into the catalytic pyrolysis a).
