Abstract:
In this study we focus mainly on the behavior of model biomass in hydrothermal pretreatment which would lead to better understanding of effective biomass raw material. Experiments for hydrothermal pretreatment were proposed to study the behavior of model biomass on continuous ¬flow system in terms of the effect of temperature, flow rate, residence time, and feed stock concentration. The experimental conditions were temperatures between 180 and 275°C, a pressure of 8 MPa, and flow rate of 40¬80 mL/min using a continuous¬flow reactor. Cellulose powder, 20¬.m from Sigma Aldrich, was used as raw material with varying concentration in the range of 0.1¬0.5 wt%. At 0.1 wt%, the cellulose dissolved more effectively than at 0.5 wt%. The plausible reason could be the cellulose at 0.5 wt% was closer to the saturated condition than the cellulose at the 0.1 wt%. Solid product was observed by SEM (Scanning Electron Microscope) and it was shown that the cellulose fibers were dissolved.
