Abstract

The feasibility of fractionating Scots pine (Pinus sylvestris L.) wood employing γ-valerolactone (GVL)/water mixtures was here studied. Pine sawdust exhibited high recalcitrance to GVL/water fractionation, with only about 50% of lignin being extracted without compromising the cellulose yield. Kinetic parameters for delignification and carbohydrate degradation during cooking were determined. In addition, GVL/water fractionation of pine wood chips yielded high amount of rejects, even when prehydrolysis was employed. Alternative pretreatment methods are being investigated.
