Hydrolysis of Lignocellulosic Biomass in Hot-Compressed Water with Supercritical Carbon Dioxide.

ABSTRACT: This study investigated the decomposition behavior of bamboo under hydrothermal and hydrolysis conditions with H₂O/CO₂ in a semicontinuous-flow reactor at 9.8 MPa. At 255 °C, with and without CO₂, xylan in bamboo completely decomposed into xylo-oligosaccharide (XOD). The yield of glucan degradation products with CO₂ was significantly higher compared with that under the hydrothermal reaction (25.7 vs 14.9 wt %, respectively). The reaction rate of glucan decomposition with CO₂ was slightly higher than the rate of hydrothermal reaction (k _H2O/CO2 /k _H2O = 1.3). Increasing the fluid velocity of the hydrothermal reaction (3-10 mL/min) significantly accelerated the solubili
