摘要

In this study, Ni/gamma-Al2O3 and Fe/activated carbon (AC) catalysts were prepared by an incipient impregnation method and then utilized for hydrodeoxygenation (HDO) of guaiacol (GUA). The AC used in the process was derived from bamboo through steam activation. The effects of the calcination temperature, metal loading, and phosphorus addition on the HDO of GUA were systematically investigated. At 300 degrees C and atmospheric pressure, 91.52% of GUA was successfully transformed into cresol and 1,2-dimethoxybenzene in liquid phase using 10 wt% of the Fe/AC catalyst, which was calcined at 550 degrees C. Under the same reaction conditions, utilizing 10 wt% of the Ni/gamma-Al2O3 catalyst, which was calcined at 450 degrees C, resulted in 96.88% GUA conversion, producing 13.03% of cresol, 58.98% of 1,2-dimethoxybenzene, and 27.99% of 3-methyl guaiacol. Additionally, the reaction pathways of the GUA HDO were proposed based on the obtained product distributions. (c) 2021 Elsevier Ltd. All rights reserved.
