| Abstract: | A new cellulose solvent ionic liquid 1-butyl-3-methylimidazolium chloride (BMIM]Cl) was used to treat wheat straw and steam-exploded wheat straw (SEWS) in order to improve the enzymatic hy- drolysis rates, while the water was used as the con- trol. The enzymatic hydrolysis results showed that the hydrolysis rates of materials treated with BMIM]Cl were improved. The hydrolysis rate of treated wheat straw could reach 70.37% and the SEWS could be completely hydrolyzed, while hydrolysis rates of the wheat straw and SEWS treated with water were 42.78% and 68.78% under the same conditions, re- spectively. The FTIR analysis and polymerization degree measurement indicated that the hydrolysis rates improvement was attributed to the decrease of the polymerization degrees of cellulose and hemi- cellulose, the absolute crystallinity degree of cellu- lose and the increase of its reaction accessibility. |
