%X It is a common method that hemicellulose of corncob was hydrolyzed by dilute sulfuric acid to obtain hemicellulose hydrolysates. However, the hydrolysates of hemicelluloses contain not only xylose but also some inhibitors such as furfural, acetic acid and various phenol compounds. Based on the combination of multiple detoxification methods, the effect of activated charcoal in detoxification procedure was studied. The results showed that the activated charcoal GH-13 and GH-15 were effective for detoxification of the hydrolysate. The more the activated charcoal charge, the less the content of inhibitors in the hydrolysate, but the more xylose loss. GH-15 of 5% (W/V) was best for detoxification of the hydrolysate and acetic acid of 24.60% and furfural of 100% were removed in the condition, the R280 was 0.009, which stands for removal of phenolic compounds in hydrolysates, but xylose of 23.70% was lost in the process.
