Abstract

Oil palm empty fruit bunch (EFB) fibers were pretreated using sodium carbonate (Na2CO3) before the hydrolysis process to produce reducing sugars by diluted sulphuric acid (H2SO4). Na2CO3 with different total titratable alkali (TTA) was used to study its effect on the physical and chemical properties of the EFB fibers and the efficiency in the acid hydrolysis process for producing reducing sugars. Results show that 10% TTA is the optimum concentration to remove lignin while preserving the polysaccharides for the EFB fibers. Silica was removed after the pretreatment process due to the swelling of the fibers. The 10% TTA of Na2CO3 offers the optimum reducing sugar yield, i.e., 62.53%, 70.34% and 72.95% for the acid hydrolysis using 0.25 N, 0.5 N and 1.0 N H2SO4, respectively.
