Abstract

Study on lignin isolation from oil palm empty fruit bunches have been done by using batch method. The optimum lignin isolation method was achieved through this study. The study was conducted on the optimization of reaction temperature, mass ratio of NaOH to the solvent, the ratio of fibers to solvents, and reaction time. Of all the treatments, it was found that the reaction optimum temperature,system pressure, concentration of NaOH, the ratio of fibers to solvents and reaction time respectively, 170 °C, 15 atm, 1% (w/v), 9% (w/v), and the reaction was carried out for 5 hours.
