It is being considered to pyrolyze lignin-rich biomass samples (hazelnut shells, HSs) into bio-fuels and chemicals to solve energy shortages and environmental concerns, volatile products (including liquid products and gas products) were produced and characterized from HSs pyrolysis at 400–1000 °C. With the temperature increases, the maximum output of liquid products was up to 35.79% produced at 700 °C, gas products yields increased from 21.82 to 55.46%. Gas chromatography and mass spectrometry (GC–MS) study indicated that liquid products from HSs riched in phenolic compounds, exceed 42% of liquid products and increased as the temperature rises. The application experiment showed that HSs liquid products had a significant role in antioxidant activity, and revealed that not limited to phenols, all compounds containing phenolic hydroxyl structure act as antioxidant. Composition analysis of gas products showed that more combustible gases were produced at the higher temperature, resulted in the significant increase in gas products higher heating value (HHV) from 6.21 to 24.36 MJ/kg.

热解温度对榛子壳挥发性产物的影响：液体产物的产物特性和抗氧化活性评估

正在考虑将富含木质素的生物质样品（榛子壳，HS）热解为生物燃料和化学品，以解决能源短缺和环境问题，生产了挥发性产品（包括液体产品和气体产品），并在400℃下通过HS的热解进行了表征–1000°C。随着温度的升高，在700°C时液体产品的最大产量高达35.79％，气体产品的产率从21.82提高到55.46％。气相色谱和质谱（GC-MS）研究表明，富含酚类化合物的HS的液体产品超过了液体产品的42％，并且随着温度的升高而增加。应用实验表明，HSs液体产品在抗氧化活性方面具有重要作用，并显示不仅限于酚类，所有含有酚羟基结构的化合物都可作为抗氧化剂。气体产品的成分分析表明，在较高温度下会产生更多的可燃气体，导致气体产品的较高热值（HHV）从6.21到24.36 MJ / kg的显着增加。
