【 摘 要 】

The sugarcane industry has huge potential for biorefinery concept application, given its development in recent years. In this context, cane sugar straw has become an attractive raw material for biofuel production. This study aims to investigate the chemical composition of cane sugar straw from different regions of Brazil, and to optimize a hydrothermal pretreatment stage for cellulosic ethanol production. Results of chemical characterization of the cane sugar straw for the regions assessed indicated little influence of place on straw chemical composition. Hydrothermal pretreatment showed high efficiency in hemicellulose removal. Hydrothermal pretreatments operating with temperatures of 190 and 210 ºC presented satisfactory results, reaching values close to 100% hydrolysis.
