Abrégé

The present invention relates to a process for producing biochar from biomass material in a reactor comprising the following steps: -supplying biomass material (100) into a material chamber (10) of the reactor; - drying the biomass material (100) by evaporating moisture from the biomass material (100); -pyrolysing the biomass material (100) to obtain biochar (105) and pyrolysis gas (106); -supplying gasification air (108) and pyrolysis gas (106) to a reaction chamber (30) in the reactor; -combustion of gasification air (108) and pyrolysis gas (106) in the reaction chamber (30); -removing exhaust gas (110) from the reaction chamber (30); -heating the biomass material (100) by indirect heat from the exhaust gas (110). The present invention relates also relates to a reactor for producing biochar from biomass material (100).
