This study is focused on understanding the hydrodeoxygenation (HDO) kinetics of pyrolysates from lignin such as phenol, guaiacol and syringol over H-ZSM-5 catalyst. The major products from syringol were guaiacol, phenol, anisole, cresol, benzene, and toluene. A reaction network was proposed to capture the transformations of syringol in which the transformations of guaiacol and phenol were included. A kinetic model comprising nine reactions of seven species was developed. The simulated yields of a majority of the HDO products matched well with experiments in the temperature range of 350-500 °C, substantiating that the obtained rate parameters reasonably represent the HDO kinetics.

这项研究的重点是了解H-ZSM-5催化剂上木质素（如苯酚，愈创木酚和丁香酚）的热解产物的加氢脱氧（HDO）动力学。丁香酚的主要产品是愈创木酚，苯酚，苯甲醚，甲酚，苯和甲苯。提出了一个反应网络以捕获丁香酚的转化，其中包括愈创木酚和苯酚的转化。建立了包括七个物种的九个反应的动力学模型。大多数HDO产品的模拟产率与350-500°C温度范围内的实验非常吻合，证明所获得的速率参数合理地代表了HDO动力学。
