STEAM EXPLOSION PULPING OF OIL PALM EMPTY FRUIT BUNCH FIBER

Xiwen Wang, Jian Hu, Jingshan Zeng

Abstract


Steam explosion pulping was evaluated for oil palm empty fruit bunches fiber. The fiber morphology was observed by SEM and TEM. Results indicated that lignin was molten and the cell wall damaged after the steam explosion pulping and that the fiber was partly separated at the same time. The results of handsheet tests showed that the steam exploded pulp had a high yield (78.2%), good physical properties (especially for ring crush 8.6 N•m/g), and low effluent load (SS=910 mg/L; BOD5=3952 mg/L; CODCr=8140 mg/L). The SEP pulp from oil palm EFB fiber was very suitable for packaging paper when combined with American OCC pulp.
