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.
