Abstract

Two established chemical delignification method employing sulfuric acid and sodium hydroxide are often used for lignocellulosic material. In this study, the enzymatic hydrolysis of coconut coir with 1.5% dilute sulfuric acid delignification at 105°C  were evaluated. This reaction is one of the stages in the process of converting lignocellulosic biomass into alternative fuels. The reducing sugar as a product of enzymatic hydrolysis can be further fermented to yield bioethanol or biohydrogen. Experiments were conducted for various concentrations of coconut  fiber (i.e. 0.1; 0.2; 0.4; 1 and 2 g/100mL).  Data from the experiment were then modeled by the power model so that the parameters can be determined. It was found that model parameters were different for each coconut fibre concentrations. The power model fits well with the experimental data as indicated by their R2 values.
