| Abstract | The influence of temperature (150-190 °C), time (0-20 min), liquid/solid-ratio (6-8) and sulphuric acid concentration (0.1-0.5 %), on the hydrolysis of palm empty fruit bunches (EFB) was studied and the liquid and solid fractions were analyzed. Polynomial models were found to reproduce the experimental results with errors less than 15 % in most of the cases (except for xylose concentration). Operating conditions of 190 °C for 15 min at a liquid/solid ratio of 6 and a sulphuric acid concentration of 0.1 % resulted in the production of 3.12, 4.0, 2.35 and 2.28 g/L of glucose, xylose, arabinose and acetic acid, respectively, starting with 1000 g of EFB. The yield was 67.96 %. Soda-anthraquinone, ethanol and ethanolamine pulping processes of the solid fraction provided pulps with brightness values of 63.24 %, 28.78 %, 48.76 %, respectively, but with poor resistance properties (6.57-8.54 N·m/g for the tensile index, 0.38-0.44 KN/g for the burst index and 0.96-1.02 mN·m2/g for the tear index). Therefore it is advisable to use the pulps for specialty papers or for bioethanol production. |
