Abstract
A method for treating plant based raw material with an enzymatic hydrolysis. The plant based raw material is treated to form lignocellulosic material. The lignocellulosic material or a solid fraction thereof is subjected to the enzymatic hydrolysis. The method includes treating the plant based raw material in at least one treatment stage for forming the lignocellulosic material including over 80% fine solid particles that are fiber-like or indefinable particles smaller than 0.2 mm and the viscosity of the lignocellulosic material is below 18000 mPas at 15% dry matter content. The method further includes subjecting the lignocellulosic material or at least one solid fraction thereof into the enzymatic hydrolysis for forming a lignin based material. The method further includes subjecting the lignin based material into at least one solid-liquid separation stage after the enzymatic hydrolysis and separating a lignin fraction and a soluble carbohydrate containing fraction.
