Hydrodeoxygenation reaction (HDO) of anisole using FePt bimetallic catalysts

Resumo

The hydrodeoxygenation reaction (HDO) represents an important way to upgrade bio-oil, and bimetallic catalysts, as FePt, can play an important role in this process due to the bifunctional mechanism. To evaluate the potential application of these catalysts and the impact of Fe content, the reactions of preferential oxidation of CO (PROX-CO) and HDO were executed in this work. The results shows that, on PROX-CO, 1Fe:1Pt/SiO2 has a better perfomance due to the moderate content of Fe compared with Pt and consequently formation of Fe-Pt alloy in the catalyst. However, for HDO of anisole, the 2Fe:1Pt/SiO2 shows the best selectivity to the deoxygenation route, indicating that different catalytic sites are stabilized under each reaction conditions.
