PROCESS FOR PRODUCING BTX BY CATALYTIC PYROLYSIS FROM BIOMASS WITHOUT RECYCLING OXYGENATED COMPOUNDS

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 le...

Beschreibung
Zusammenfassung:	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.
