Abstract
A process is described for producing a BTX cut from biomass comprising at least one step of catalytic pyrolysis of said biomass in a fluidized-bed reactor in which a stream comprising at least one oxygenated compound selected from alcohols having 2 to 12 carbon atoms, alcohol acids having 2 to 12 carbon atoms, diols having 2 to 12 carbon atoms, carboxylic acids having 2 to 12 carbon atoms, ethers having 2 to 12 carbon atoms, aldehydes having 2 to 12 carbon atoms, esters having 2 to 12 carbon atoms and glycerol, alone or mixed, is fed into the catalytic pyrolysis reactor.
