The invention relates to a method and apparatus for producing liquid hydro carbonaceous product (1) such as biofuel from solid biomass (2). The method comprises a gasifying step for gasifying solid biomass (2) in a gasifier (6) to produce raw synthesis gas (3), conditioning of the raw synthesis gas (3) to purify the raw synthesis gas (3) to obtain purified synthesis gas (4) having a molar ratio of hydrogen to carbon monoxide between 2.5 to 1 and 0.5 to 1, preferably to between 2.1 to 1 and 1.8 to 1, more preferably about 2 to 1, and subjecting purified synthesis gas (4) to a Fischer-Tropsch synthesis in a Fischer-Tropsch reactor (5) to produce liquid hydro carbonaceous product (1).
L'invention concerne un procédé et un dispositif permettant de produire un produit hydrocarboné liquide (1) tel que du biocarburant à partir d'une biomasse solide (2). Le procédé comprend les étapes consistant à: gazéifier la biomasse solide (2) dans un gazogène (6) pour produire un gaz de synthèse (3) brut; conditionner le gaz de synthèse (3) brut pour purifier ledit gaz (3) afin d'obtenir un gaz de synthèse (4) purifié présentant un rapport molaire hydrogène/monoxyde de carbone compris entre 2,5/1 et 0,5/1, de préférence entre 2,1/1 et 1,8/1, et idéalement d'environ 2/1; et soumettre le gaz de synthèse (4) purifié à une synthèse de Fischer-Tropsch dans un réacteur de Fischer-Tropsch (5) afin de produire un produit hydrocarboné liquide (1).
