Researchers studied how to break down corn stalks using a weak acid. They looked at factors like temperature, time, acid concentration, and corn stalk size. They found that at 126℃, with 50-80 g/L of corn stalk, 1% acid, and 1 hour, they could get 21.7%-24.6% of the corn stalk to break down, yielding 68.0%-77.1% xylose. The liquid produced mainly contains xylose and glucose, which can be used for fermentation after a simple process.
