This research evaluated a catalyst activity for hydrodesulfurization (HDS) of a petroleum fraction and the mixture of partially hydrodeoxygenated bio-oil (HBO), which was hydrodeoxygenated woody tar (HWT) and the petroleum fraction, which was light gas oil. As results, 340ºC of reaction temperature and 2 hours of reaction period provide positive influence on the catalyst activity. Oxygen and nitrogen compounds in bio-oil exhibit an inhibiting effect on the HDS. Synthesized catalysts supported on titanium-rich and pure titania carriers indicate higher activity than those supported on pure alumina, since TiO2 acts as an electronic promoter in catalysts. The electronic promotion of Mo by Ti has a limitation, accordingly, 310CoMoAT (1:0.75) catalyst presents the best catalytic behavior. The approach from this research can contribute a direction for further improvement of co-processing bio-oil productions as a sustainable fuel invention.
