Abstract

The work investigated performances of several CoMoP and CoMoW catalysts supported on different carbon materials in catalytic hydrodeoxygenation (HDO) of pyrolysis oil in supercritical ethanol using formic acid as an in-situ hydrogen source. Among them, the CoMoP catalyst supported on ZnCl₂ activated sawdust carbon (ASC-Zn) and the CoMoW catalyst supported on multi-walled carbon nanotubes (MWNTs) showed the best HDO performance at both 300 °C and 350 °C for 2 h, obtaining higher upgraded oil yield, lower oxygen contents of the upgraded oils, and higher degrees of deoxygenation (DOD). Whereas the stability tests with three HDO cycles showed that both catalysts were slightly deactivated likely by active metals leach-out or coke/carbon deposition on active sites of the catalysts. © 2023 Elsevier Ltd.
