Hydrodeoxygenation of dibenzofuran over noble metal supported on mesoporous zeolite

Hydrodeoxygenation has been considered to be one of the most promising methods for bio-oil upgrading. In this paper, the catalytic performance of noble metal supported on mesoporous zeolite in model bio-oil compound hydrodeoxygenation was examined. Dibenzofuran was chosen here because of its refractory nature and large molecular size. Our results indicate that Pt supported on mesoporous ZSM-5 show better performance in dibenzofuran hydrodeoxygenation than Pt/ZSM-5 and Pt/Al2O3. The excellent catalytic performance is attributed to the combination of strong acidity and mesopore structure in mesoporous zeolite.

► Zeolite with wormhole like mesopore channel is used as support for noble metal.
► Pt on mesoporous ZSM-5 show better performance in dibenzofuran hydrodeoxygenation.
► The combined acidity and mesoporisity is reasonable for the performance improvement.
