Abstract Fast pyrolysis is traditionally defined as the rapid decomposition of organic material in the absence of oxygen to produce primarily a liquid product known as bio-oil. However, the introduction of small amounts of oxygen to the process holds prospects of internally generating the energy needed for pyrolysis. The present study investigates the partial oxidation of lignin-derived compounds during pyrolysis, which generates both carbon oxides and aromatic carbonyl compounds. Analysis of lignin derived phenolic compounds was performed to determine if the composition had changed under oxidative conditions. NMR analyses indicates aromatic carbonyls increased under oxidative conditions, with a corresponding decrease in phenolic hydroxyl groups. Model phenolic compounds were pyrolyzed to help understand the role of partial oxidation during autothermal pyrolysis of lignocellulosic biomass.

木质纤维素自热裂解过程中酚类化合物的氧化

摘要 快速热解传统上定义为有机材料在无氧条件下的快速分解，主要产生称为生物油的液体产品。然而，向该过程引入少量氧气具有在内部产生热解所需能量的前景。本研究调查了木质素衍生化合物在热解过程中的部分氧化，这会产生碳氧化物和芳香羰基化合物。对木质素衍生的酚类化合物进行分析以确定在氧化条件下组成是否发生变化。NMR 分析表明在氧化条件下芳族羰基增加，酚羟基相应减少。
