Source evidence

The SF at 4.00 (165 °C–122 min) with the 0.005% NaOH produced the 88.71% maximum yields of xylo-sugar (73.78%, 12.61% and 2.32% for xylose, XOS and xylan) while the formation of inhibitors still remained at low levels.

Abstract evidence

The highest xylo-sugars yield of 88.71% was achieved when 0.005% NaOH was employed as the deacetylation agent and the severity factor was 4.00. Meanwhile, the unknown loss of hemicelluloses was limited to 1.51% (based on the total hemicelluloses in corncob) and the formation of furfural was also limited at the low level (1.72%).

Equipment and method evidence

MIHP was performed in a 100 mL closed-vessel PTEF microwave reactor (600 W, GAS-800, Beijing Xianghu Science and Technology Development Reagent Co., Ltd., Beijing, China).
