Abstract:
HDO of fast pyrolysis bio-oil shows potential in generating renewable and low-carbon liquid fuels. Catalytic HDO encompasses a series of reactions involving oxygenated organic molecules under pressurized hydrogen and the presence of an active catalyst, resulting in the reduction of the degree of oxygenation. The choice of catalyst support shape, whether pelletized or powdered, can significantly influence catalytic activity and stability. This work compares the performance of powdered and pelletized niobium oxide (Nb2O5)-based catalysts during batch-HDO, and evaluates the performance of pelletized catalysts in a continuous trickle reactor. Guaiacol is used as a representative of bio-oil. The study aims to provide an understanding of the variations in catalytic activity, selectivity, and stability between the two forms of catalysts, thereby offering valuable insights into their suitability for large-scale continuous HDO applications. By comprehending the unique characteristics and performance qualities of pelletized and powdered catalysts, the advancement of efficient and scalable catalyst systems for bio-oil refining can be facilitated.
