Factorial analysis on nitric acid pretreatment of oil palm frond bagasse for xylan recovery
Hemicellulose in agricultural biomass are composed mainly of xylan which can be used for various application of valuable products including xylooligosaccharides. The aim of this work is to study the factors affecting acid pretreatment of oil palm frond bagasse for xylan recovery. The half fractional...

Hemicellulose in agricultural biomass are composed mainly of xylan which can be used for various application of valuable products including xylooligosaccharides. The aim of this work is to study the factors affecting acid pretreatment of oil palm frond bagasse for xylan recovery. The half fractional two-level factorial design with five factors was selected for the experimental design. The studied factors were nitric acid concentration (0.1 - 1.0%), temperature (37 - 90 °C), time (6 - 24 hours), solid loading (5 - 20%) and agitation (yes/no). The highest concentration of xylan at 0.5 g/L was obtained during pretreatment at 37 °C for 24 hours with 5% solid loading and 0.01% acid concentration without agitation.
