摘要
To achieve green hydrolysis technology of hemicellulose through repeated using hydrolysate, the hydrolysis of hemicellulose in corncob was studied. The influence of repeated use of corncob hydrolysate on concentrations of d-xylose and l-arabinose was investigated. The loss rates of d-xylose in the prepared d-xylose solutions both with and without corncob, and repeated using corncob hydrolysate under identical acidity condition were discussed. The result shows that d-xylose concentration and l-arabinose concentration are all gradually increasing with the growing time of repeated use of corncob hydrolysate. After the fifth repetition, the concentrations of d-xylose and l-arabinose are 196.7 g·L− 1 and 22.0 g·L− 1, respectively. Substance inhibiting the degradation of d-xylose is generated during repeated use of corncob hydrolysate, and the production is further proved by the change of d-xylose concentration and the loss rate of d-xylose over heating time.
