Corn stover was treated with a weak acid to get a lot of xylose and a bit of glucose from it, saving resources and fully utilizing the stover. The researchers wanted to optimize the process to get more xylose compared to glucose. By testing different conditions, they found that using 2.4% sulfuric acid for 100 minutes at 100°C gave the best results. At these settings, about 78.8% of the xylose was recovered, while less than 11.6% of glucose was produced. When they tried this out, the actual numbers were close, with 78% xylose and 11.3% glucose in the end.
