Study on Dilute Sulfuric Acid Hydrolysis of Corn Stover

Abstract:

The object of this research is to investigate the factors influencing the hydrolysis of corn stover by dilute sulfuric acid and the types of sugars existed in hydrolysate. Experiment results showed that the optimal conditions were hydrolysis temperature 120°C, stover size 20-40 mesh, soak time 36h, reaction time 100 min, H₂SO₄ concentration 1.5% and solid-liquid ratio 1:8. Sugars gained in the hydrolysate were xylose 3.0%, glucose 0.71%, mannose 0.12% and galactose 0.32% determined by capillary electrophoresis.
