Kinetic studies on acid hydrolysis of Meranti wood sawdust for xylose production

Meranti wood sawdust (MWS) is a lignocellulosic waste of sawmill which can be used as a promising source of xylose. The main application of xylose is its bioconversion to xylitol, a high value product. The growing interest in biotechnological production of biofuels and specialty chemicals from lig...

Optimum sulfuric acid concentration and residence time obtained were 6% and 20 min, respectively. These conditions yielded a hydrolysate containing 18.5, 4.2, 0.4, and 4.1 g/l xylose, glucose, furfural, and acetic acid, respectively. The yield of xylose was more than 89% of the potential concentration.
