Resumen
QUILA (CHUSQUEA QUILA) IS A VERY ABUNDANT NATIVE CHILEAN BAMBOO SPECIES. THIS WORK REPORTS ON A DELIGNIFICATION PROCESS WHICH CAN BE APPLIED TO QUILA TO PRODUCE CRYSTALLINE CELLULOSE, AN IMPORTANT RESOURCE FOR OBTAINING CELLULOSE NANOFIBRES OR NANOCRYSTALS. ALTERNATIVELY, THE CRYSTALLINE CELLULOSE CAN THEN BE SUBJECTED TO FERMENTATION PROCESSES, MAKING IT A USEFUL RAW MATERIAL FOR BIOFUEL PRODUCTION. THE TREATMENT STUDIED IS AN OXIDATIVE TREATMENT AT LOW CONCENTRATION (15% V/V), FOR SHORT TIME PERIODS (10, 20 MIN) AND AT TEMPERATURES BETWEEN 100 AND 140 °C, WHICH PRODUCES ALPHA-CELLULOSE FIBRES WITH HIGH CRYSTALLINITY (OVER 70%) AND LOW RESIDUAL LIGNIN CONTENT (
