| description | Oil palm empty fruit bunch (OPEFB) is one of the prominent
lignocellulosic wastes from the oil palm industry, and it has the potential for
feedstock in biobased products. However, delignification must be applied. This
study investigated the effect of microwave-assisted alkaline pretreatment of OPEFB
by using response surface methodology with Box-Behnken design (BBD) to find the
optimum pretreatment conditions. OPEFB (30-mesh) was treated with various
concentrations of aqueous sodium hydroxide. The effect of three variables,
microwave power (280-840 W), NaOH concentration (1-3% w/v), and reaction time (3-9 min), was
evaluated to improve lignin removal. The quadratic model indicated that
microwave power of 832.9 W, NaOH concentration of 2.7% (w/v), and a reaction
time of 8.9 min resulted in the highest lignin removal: 88.10%. FTIR and SEM
analysis was also conducted on the untreated and treated OPEFB to evaluate the
effectiveness of the pretreatment. These results
showed that microwave-assisted alkaline pretreatment of OPEFB could effectively
remove the lignin under a relatively short time period and low alkaline
concentration. |
