Simulation of Barley Straw Acid Hydrolysis to Fermentable Oligosaccharides and Monosaccharides for Bioethanol Production

D.K. Sidiras
The aim of this research is to study dilute sulfuric acid catalyzed hydrolysis of barley straw cellulose and hemicelluloses, employing a batch reactor. Process parameters investigated include variation in reaction ending temperature (160 ­ 220°C) and reaction time (0 50 min). A new kinetic model, incorporating a Severity Factor X or in logarithmic form logX, was developed simulating the process. Significant sugar degradation occurred at these conditions and the optimum yield was 37.7% for total...
