Example Embodiment
[0024] Example 1
[0025] In the prepared flask, add 600 g of water, H 2 SO 4 6g and 80g of straw (water 10%, the same below), then heated to 90-100°C for 1 hour; the amount of sugar (mainly xylose) obtained is 11g. The sugar solution is used for fermentation to produce ethanol.
Example Embodiment
[0026] Example 2
[0027] In the prepared flask, add 600 g of water, H 2 SO 4 5g, 1g of HCl and 80g of straw, and then heated to 90-100°C for 1 hour; the amount of sugar (mainly xylose) obtained was 12.5g. The sugar solution is used for fermentation to produce ethanol.
Example Embodiment
[0028] Example 3
