Co-processing of pyrolisis bio oils and gas oil for new generation of bio-fuels:Hydrodeoxygenation of guaı¨acol and SRGO mixed feed

---

Abstract.
Within the frame of second generation bio-fuels development, the present work reports for the first time
the impact of co-processing guaiacol as an oxygenated molecule representative of pyrolitic bio oils with
a straight run gas oil (SRGO) in the framework of a hydrodesulfurization process (HDS). The reaction
scheme observed during the hydrotreating of the sole guaiacol in the gas phase was compared to the
conversion products observed during the co-processing of guaiacol with the SRGO, by using the two
dimensional GC–MS analysis. During the co-processing, a decrease of the HDS performance of a reference
CoMo/Al2O3 catalyst was observed at low temperature and high contact time. It was assigned to the
formation of intermediate phenols competing with sulfur containing molecules for adsorbing on
hydrogenation/hydrogenolysis sites. Above 320 oC, complete hydrodeoxygenation (HDO) of guaiacol
was observed and HDS could proceed without any further inhibition
