The present invention relates to a method for defibrating a lignocellulosic material in a steam explosion process, the method comprising: —supplying (1001) lignocellulosic material to a reactor (8), —treating (1002) the lignocellulosic material in the reactor (8) at a first pressure (P1), —discharging (1003) the lignocellulosic material from the reactor (8) to a vessel (13), wherein the vessel (13) is at a second pressure (P2) that is lower than the first pressure (P1) so that the lignocellulosic material is defibrated through steam explosion as it passes from the reactor (8), wherein lignocellulosic material is continuously supplied to and discharged from the reactor (8) in such a way that the first pressure (P1) is constant. The invention also relates to a defibration system for defibrating a lignocellulosic material in a steam explosion process.

The invention relates to a method for treating biomass (2). Biomass (2) is fed to a pressurized prehydrolysis reactor unit (8) by means of a feeding system (5, 7), wherein by means of the feeding system (5, 7) the biomass (2) is compressed. A filtrate is squeezed out of the biomass (2) by means of the feeding system (5, 7), in particular by a first plug screw (5) or a second plug screw (7) of the feeding system (5, 7). The biomass (2) is then thermally treated in the pressurized prehydrolysis reactor unit (8), discharged from the pressurized prehydrolysis reactor unit (8) afterwards, diluted with the filtrate before or after the discharge, and treated with an enzyme subsequently.

A process for the production of particle board, MDF board or HDF board includes the step of recycling particle board material, MDF and/or HDF board material in which recycled chips and/or recycled wood fibers are produced. The process includes the step in which the particle board material, the MDF and/or HDF board material is wetted, heated and pressurized, such that this material is kept under pressure and at an elevated temperature for a certain time. The process involves the step of supplying the recycled chips and/or the recycled wood fibers as base material in a production process of particle board, MDF board or HDF board.
