High glucose selectivity in pressurized water hydrolysis of cellulose using ultra-fast reactors

► Total cellulose hydrolysis to glucose and oligomer can be achieved with residence times 0.02-0.03 s. ► Very low concentration of derived-products by the control of the residence time. ► The ultra fast reactor allows the control of extremely low the residence time. ► The supercritical water medium avoids the ionic degradation reactions. ► The residence time could control the glucose radical degradation reactions.
