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.

Abstract: A method for producing mono-ethylene glycol (MEG) from a wood-based raw material, and wherein method includes: i) providing a wood-based feedstock originating from the wood-based raw material and including wood chips, wherein at most 5 weight-% of the wood chips in the wood-based feedstock are overthick wood chips as specified by SCAN-CM 40:01, and subjecting the wood-based feedstock to at least one pretreatment to form a liquid fraction and a fraction including solid cellulose particles; ii) subjecting the fraction comprising solid cellulose particles to enzymatic hydrolysis to form a lignin fraction and a carbohydrate fraction; iii) subjecting the carbohydrate fraction to catalytical conversion to form a liquid composition of glycols; and iv) recovering mono-ethylene glycol from the liquid composition of glycols. Further is disclosed a corresponding arrangement and mono-ethylene glycol obtainable by the method.

Abstract: Method and control system are provided for controlling values of process parameters of a pretreatment process of wood particles. A sampler is used to obtain a sample of a product flow of said pretreatment process after said wood particles have undergone steam explosion in a hemihydrolysis reactor. A particle measurement device is used to measure one or more characteristics of particles in said sample and to produce one or more pieces of measurement information indicative of the measured characteristics. Said one or more pieces of measurement information are used to select one or more values of one or more of said process parameters.

Abstract: In a method and an apparatus furfural is recovered from a steam stream (3) which is formed in a treatment of a pretreated wood based material (1). The pretreated wood based material (1) which comprises at least carbohydrates is treated in a steam treatment stage (2) in which the steam is released. The steam stream (3) which comprises furfural is supplied out from the steam treatment stage (2). A pretreated and steam-treated wood based material (4) which comprises carbohydrates is supplied out from the steam treatment stage (2), and the steam stream (3) is treated in a recovery stage (12a, 12b) for recovering a furfural based fraction (14a,14b).
