Turning Rice Straw into Valuable Sugars Could Boost Biofuel Production
Researchers used dilute sulfuric acid to treat rice straw and studied how different reaction conditions affected the production and breakdown of its components. They found that arabinose production and xylose breakdown were the most significant. The highest hemicellulose yield achieved was around 80%, with higher acid concentrations leading to better results. However, high temperatures did not have the same positive effect. The best conditions for maximum yield were at 140°C, 2.5% acid concentration, and 20 minutes of reaction time. Glucose yields remained consistent regardless of the reaction conditions.
