Abstract:
A process is disclosed for conversion of cellulose in an Ionic Liquid medium. The process is characterized in that a cellulose-containing feedstock and an Ionic Liquid are mixed at a temperature below 80 °C. The mixture is heated to a conversion temperature in the range of 80 °C to 220 °C under a hydrogen atmosphere. The presence of hydrogen during the heating step significantly reduces the formation of degradation products.
