Kuvaus

We present a mathematical model for the yield loss and decline in polymerization of carbohydrates. The model is applicable to the treatment of cellulose and hemicellulose in alkaline media and it features the actions of peeling, stopping and alkaline hydrolysis on the polymer chains. The reaction rates are estimated by fitting the model to experimental data. Experiments conducted at several temperatures enable the evaluation of activation energies for the reactions. The peeling reaction is further divided into primary and secondary peeling, depending on whether it originates from an initial reducing end group or from a reducing end group created by alkaline hydrolysis. We are able to evaluate the impact of the different processes on degradation and the portion of polymer chains possessing reducing end groups.
