Abstract
Willow without any pretreatment, and water were studied in an optical micro-reactor, diamond anvil cell by rapid heating (7-10°C/s) to high temperatures and high pressures (up to 403°C and 416 MPa), most of willow (89-99%) dissolved and hydrolyzed in water at 330-403°C within 22 s. It was found that low-density water (e.g., 571 kg/m(3)) solubilized almost all willow with particle size less than 200 μm, and subsequently hydrolyzed to hydrolysates in subcritical water at 354°C and 19 MPa within 9 s. These results were further used to propose a flow process to fast hydrolyze wood in seconds to valuable sugars.
