EXTRACTION AND CHARACTERIZATION OF HEMICELLULOSES AND CELLULOSE FROM OIL PALM TRUNK AND EMPTY FRUIT BUNCH FIBRES

摘要

The cell walls of oil palm trunk fibre and empty fruit bunch (EFB0 fibre were initially extracted with 5/100 NaOH at boiling for 2 h, which removed 17.3/100 and 15.2/100 hemicelluloses, respectively. Further extraction of the delignified palm trunk and EFB fibre was conducted with 10/100 NaOH at 20 deg. C for 16 h and 24/100 KOH- 2/100 H_3BO_3 at 20 deg. C for 2 h. This resulted in the release of 11.9/100, 13.5/100, 12.7/100 and 14.9/100 residual hemicelluloses, respectively.
