Abstract:
    A process for the recovery of furfural, furfuryl alcohol, low molecular weight phenols and/or cellulose or a cellulose-rich material from a lignocellulosic material comprising: feeding a carrier gas into a reaction chamber to facilitate a fluidised bed effect and to carry reaction products and residues away from the reactor via entrainment; introducing a feedstock comprising particulate lignocellulosic material of a predetermined particle size into the reaction chamber; degrading the feedstock in the reaction chamber under an oxygen-containing atmosphere at a temperature of from 250 DEG C to 320 DEG C; and quenching the degraded feedstock and carrier gas to deposit solid residues entrained in the carrier gas and to condense a liquid product.
