Evaluating and optimizing pretreatment technique for catalytic hydrogenolysis conversion of corn stalk into polyol

, : Evaluating and optimizing pretreatment technique for catalytic hydrogenolysis conversion of corn stalk into polyol. Bioresource Technology 158: 307-312

A combinative pretreatment technology of steam explosion (SE) and alkali was applied to enhance hydrogenolysis conversion of corn stalk into polyol with Ni-W2C or Fe-Mn-K catalyst. The results showed that treatments corn stalk with 0.4 MPa SE and alkali removed 84.16 wt% of hemicellulose and 71.83 wt% of lignin and thereby increased the cellulose content from 31.54 to 80.41 wt%. But the glucose loss was insignificant during pretreatment. Data from catalytic hydrogenolysis showed that pretreatment corn stalk with 0.4 MPa SE and alkali improved the yield of polyol, and about 20.38 wt% of ethylene glycol and 52.36 wt% of glycerol were produced after catalysis with Ni-W2C/(coconut shell activated carbon, CSAC). Based on the yield of polyol, the catalytic performance of Ni-W2C/CSAC was significantly better than those of Ni-W2C/(coal-based activated carbon) and Fe-Mn-K/(amorphous carbon).
