Abstract: The hydrolysis of corn stalks and hydrolysate refining were studied. The results showed that the hydrolysis rate of hemicellulose and cellulose at 120℃ were 93.7% and 19.7%, respectively. The hydrolysis rate of hemicellulose and cellulose at 160℃ were 98.1% and 73.4%, respectively. 96% hydroxy-benzene, 94% cation, 96% weak acid and mineral acid of the hydrolysate can be removed by adsorptive resin, anion resin and cation resin.

Key words: corn stalks, hydrolysis, refining
