Kinetics of the Acid hydrolysis of Sugarcane Bagasse Using Different Milling Size, High Solid Load and Low Pretreatment Temperature

Abstract

The aim of this work was to obtain experimental data in order to generate the kinetic model that showed the effect of the particle size on the performance of the pretreatment process. Data were obtained from the pretreatment kinetics process of sugarcane bagasse with dilute sulfuric acid in concentration of 1.0, 2.0 and 3.0% (w/v). The pretreatments were carried out at temperature of 121±1°C varying time and milling size, The studied times were 0, 15, 45, 60, 90 and 120 minutes and particle average diameter of 0.11, 0.25 and 0.50 mm. All the experiments were performed using a solid load of 15%.
