Hydrodeoxygenation of a bio-oil model compound derived from woody biomass using spray-pyrolysis-derived spherical g-Al2O3-SiO2 catalysts

다국어 초록 (Multilingual Abstract)

In this study, spherical g-Al2O3-SiO2 catalysts with various Al/Si ratios were prepared by combining thesol-gel and spray pyrolysis (SP) methods. The effectiveness of the product catalysts was then tested viathe hydrodeoxygenation (HDO) of guaiacol, a model compound of bio-oil obtained from the pyrolysis oflignocellulosic biomass. Our results showed that the g-Al2O3-SiO2 catalyst with a 50:50 Al/Si ratio aftercalcination at 450 C exhibited the highest guaiacol conversion (81.79%) at a reaction temperature of300 C, atmospheric pressure, and a weight hourly space velocity (WHSV) of 6.5 h 1. During guaiacolHDO, the carbon–oxygen cleavage and methyl group transfer reactions occurred on the g-Al2O3-SiO2catalyst, which converted the guaiacol into the respective deoxygenated products, including 2,6-xylenol,2,3,5,6-tetramethyl phenol, pentamethyl benzene, and hexamethyl benzene. The reaction pathways forthe conversion of guaiacol HDO were also proposed in this study.
