Potential Activity Evaluation of CoMo/Al2O3-TiO2 Catalysts for Hydrodesulfurization of Coprocessing Bio-oil
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 TiO 2 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.
