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...

| description | 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 lignocellulosic
waste is justifiable as these materials are low priced, renewable and widespread sources of sugars. The aim of this research was to study xylose production from MWS by acid hydrolysis. Batch hydrolysis was conducted at 130 1C using several concentrations of H2SO4 (2–6%) and residence time (0–120 min). The kinetic parameters of mathematical models were determined to predict xylose, glucose, furfural, and acetic acid concentration in the hemicellulosic hydrolysate. 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. |
