A method for collecting biomass, such as straw, and for producing a pyrolysis liquid, such as oil or tar, from the biomass, comprises the step of collecting the biomass from a growth site, e.g. a field, by means of a mobile unit. The biomass is continuously fed into a pyrolysis apparatus (200) accommodated by the mobile unit, as the mobile unit is moved across the growth site. While the biomass is processed in the pyrolysis apparatus, further biomass is simultaneously being collected. The pyrolysis apparatus may be a flash pyrolysis or fast pyrolysis apparatus relying on centrifugal forces for forcing biomass towards a reactive surface in a pyrolysis reactor. The mobile unit may be self-propelled.
La présente invention concerne un procédé de ramassage de biomasse, telle que de la paille, et pour transformer la biomasse en pyrolysat (huile, goudron, ). A cet effet, on ramasse la biomasse sur le site de production (champ, ) avec l'unité mobile. La biomasse alimente en continu un pyrolyseur (200) monté sur l'unité mobile, pendant que l'unité parcourt le site de production. Le traitement de la biomasse dans le pyrolyseur se fait pendant le ramassage. Le pyrolyseur peut être à pyrolyse flash ou à pyrolyse rapide en fonction des forces centrifuges propulsant la biomasse contre une surface de réaction dans le pyrolyseur. L'unité mobile peut être automotrice.
