It was observed that a decrease in the Si/Al ratio of the support results in an increase in the yield of cyclohexane and a decrease in the yield of 2-methoxycyclohexanol in HDO of guaiacol. This data also discloses the influence of the concentration of acid sites on the deoxygenation of 2-methoxycyclohexanol. Both Ru/BEA and Ru/ZSM-5, with both possessing low Si/Al ratios, display a high activity for HDO for guaiacol, while only the Ru/BEA catalyst exhibits a high activity for HDO of biocrude oil. Catalyst characterisation (BET, NH₃-TPD and NH₃ and acetonitrile-d3-FTIR) shows that the Ru/BEA catalyst, with a low Si/Al ratio, not only possesses strong Brønsted acid sites but also contains extensive mesoporosity. Notably, these mesopores appear to facilitate the hydrogenation, deoxygenation, and ring-opening of large oxygenated and condensed-ring hydrocarbons in biocrude oil which then leads to a high yield of cycloalkanes. As expected, the Ru/Al₂O₃ and Ru/SiO₂ catalysts exhibit a high hydrogenation activity but a lower deoxygenation activity in the HDO of guaiacol and biocrude oil. These results suggest that the larger pore support, with strong Brønsted acid sites, engendered the HDO activity observed. The reaction pathway for the main components of biocrude oil was proposed based on the observed reaction product distribution.]]> Wed 20 Oct 2021 11:28:59 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47138 Tue 14 Nov 2023 11:38:41 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42886 Tue 06 Sep 2022 11:58:22 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30924 Thu 30 Jan 2020 10:16:09 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18928 Sat 24 Mar 2018 07:58:59 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23235 3, and C-O functional groups in char samples decreased significantly after pyrolysis.]]> Sat 24 Mar 2018 07:10:39 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53576 Mon 29 Jan 2024 18:20:35 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43406 Fri 16 Sep 2022 10:54:33 AEST ]]>
