Abstract:
This work reports on the use of ion exchange resins for the hydrolysis of hemicellulose-derived oligo-saccharides (OS). Four heat-stable cation exchange resins were evaluated using natural OS in order to access their performance and selectivity to catalyse OS hydrolysis with minimal monosaccharide dehydration to furans. Under mild operation temperature (140 ºC), it was possible to achieve high hydrolysis rates and yields (close to 100%), to-gether with limited sugar degradation. Catalyst recyclability was also evaluated and reutilization up to 6 times was feasible, with minor loss of efficiency.
