| Abstract | Saccharification of lignocellulose is a necessary procedure for deconstructing the complex structure for building a sugar platform that can be used for producing biofuel and high-value chemicals. In this study, a carbon-based solid acid catalyst derived from sodium lignosulfonate, a waste by-product from the paper industry, was successfully prepared and used for the hydrolysis of hemicellulose in corncob. The optimum preparation conditions for the catalyst were determined to be carbonization at 250 degrees C for 6 h, followed by sulfonation with concentrated H2SO4 (98%) and oxidation with 10% H2O2 (solid-liquid ratio of 1:75 g mL(-1)) at 50 degrees C for 90 min. SEM, XRD, FT-IR, elemental analysis and acid-base titration were used for the characterization of the catalysts. It was found that 0.68 mmol g(-1) SO3H and 4.78 mmol g(-1) total acid were loaded onto the catalyst. When corncob was hydrolyzed by this catalyst at 130 degrees C for 12 h, the catalyst exhibited high selectivity and produced a relatively high xylose yield of up to 84.2% (w/w) with a few by-products. Under these conditions, the retention rate of cellulose was 82.5%, and the selectivity reached 86.75%. After 5 cycles of reuse, the catalyst still showed high catalytic activity, with slightly decreased yields of xylose from 84.2% to 70.7%. |
