Kinetics of the Hot-Water Extraction of Paulownia Elongata Woodchips
Hot water extraction of Paulowniaelongata woodchips was performed at different temperatures (145 °C, 155 °C and 165 °C) for 4 h, with a solid to liquor ratio of 1:8. Samples were taken every 20 min after reaching the desired temperatures. The main monomer sugar was
xylose and its maximum yield was 0.025 mol/100 g of oven-dry wood mass. The maximum yield of xylooligosaccharide was 0.051 g/100 g of oven-dry wood mass. Kinetic models were developed for dissolved solid, acetic acid, xylose, xylooligosaccharide, and furfural during hot water extraction of
Paulowniaelongata woodchips. Degradation pathway of products were described by comparing the reaction rate constants.
