Abstract

See full text

A method is provided for controlling enzymatic hydrolysis in a manufacturing process of chemical bioproducts. The method comprises performing at least one FTIR measurement on at least one process fluid, and controlling the value of at least one process parameter based on the results obtained. Said results indicate the content of one or more carbohydrates in the respective process fluid. Said controlling of the value of the process parameter is performed in order to affect at least one of: the conversion of cellulose and hemicellulose into monomeric carbohydrates in said enzymatic hydrolysis, the relative content of soluble lignin in relation to monomeric carbohydrates in said enzymatic hydrolysis.
