In the 3rst step, steam explosion lignin, as a modi3er and a binder is introduced to the lignocellulosic biomass by impregnation
or during the hot pressing process to form a hard 3berboard. By subsequent carbonisation of the 3berboard
panels or blocks, carbonised panels or blocks with high bending and crushing strength and suitable thermodynamic properties
are obtained due to the formation of an internal lignin reinforcement in cell lumina and impregnation of cell walls
with lignin solution or molten lignin. The carbonised panels demonstrate a good dimensional stability after a standard
treatment with water
