Wheat Straw Pretreatment Unlocks Sustainable Fuel Potential, Transforming Energy Landscape
The researchers studied how treating wheat straw with steam explosion and ethanol affects the structure of lignin. They separated different types of lignin and analyzed their properties using various techniques. They found that the structure of lignin changed during the pretreatment process, with some parts being transformed or destroyed. The thermal stability of one type of lignin was higher due to a condensation reaction. Overall, the pretreatment methods altered the composition and properties of lignin from wheat straw.
