A fast pyrolysis apparatus (200) for producing pyrolysis liquid, such as oil or tar, char and pyrolysis gas from biomass, such as straw, comprises a centrifuge chamber (204) and a rotor (210) arranged to impart rotation on the biomass in the centrifuge chamber to force the biomass outwardly under the action of centrifugal forces. A furnace (206) arranged coaxially around the centrifuge chamber (204) maintains the temperature at an outer reactive wall of the centrifuge chamber at an elevated temperature to effect the pyrolysis process at or near the reactive wall. The apparatus comprises a condenser (218) arranged coaxially with and surrounded by the centrifuge chamber (204). The apparatus may be accommodated by a mobile unit for simultaneously collecting biomass from a field and processing the biomass in the apparatus.

La présente invention concerne un appareil (200) à pyrolyse rapide destiné à la production de liquide de pyrolyse (huile, goudron ), de carbonisat, et de gaz de pyrolyse à partir de biomasse (paille, ). L'appareil comporte une chambre centrifuge (204) et un rotor (210) agencé pour faire tourner la biomasse dans la chambre centrifuge, et la soumettre à la force centrifuge. Un four (206) monté coaxial autour de la chambre (204) maintient la paroi extérieure de réaction de la chambre à une température élevée propre à une pyrolyse contre ou près de la paroi de réaction. L'appareil peut se monter sur une unité mobile effectuant simultanément la collecte de la biomasse dans un champ et traitant cette biomasse dans l'appareil.
