dc.description.abstractThe potential of oil palm frond (OPF) as glucose source for fuel ethanol production was investigated in this current work. Pretreatment of lignocellulosic feedstock with a solvent, ionic liquid (IL) 1-butyl-3-methylimidazolium chloride ((BMIM)Cl) was used to facilitate the conversion of OPF into fermentable sugar (glucose). The pretreatment was accomplished by first subjecting OPF to ionic liquid treatment, followed by regeneration of cellulose using an anti-solvent. The effects of several pretreatment variables, such as temperature, retention time and solid loading on the biomass composition, crystallinity as well as its digestibility by enzyme and glucose recovery after pretreatment were studied. Results showed that biomass digestibility and glucose recovery were strongly influenced by the changes in the biomass structure and composition after pretreatment but not by the crystallinity of the biomass alone. The pretreatment variables were further optimised using Response Surface Methodology (RSM) based on a factorial Central Composite Design (CCD). An optimum 100 % glucose recovery was found with pretreatment conditions of 80 °C, a 15 min retention time and 10 wt% solid loading as oppose to glucose recovery from raw OPF that was merely 22.57 % under the same conditions. Hence, pretreatment of lignocellulosic biomass using ionic liquid [BMIM]Cl is one of the promising techniques to enhance glucose recovery for the production of bio-ethanol.en_US
