Pyrolysis oil derived from lignocellulosic biomass is a promising alternative to petroleum-derived oil once we develop an efficient deoxygenation catalyst and process. In this respect, hydrodeoxygenation (HDO) of pyrolysis oil, hydrogenolysis in the presence of H2 gas and metal catalyst, has been extensively studied using a range of catalytic materials, e.g., metal-acid bifunctional catalyst, Mo-based sulfide catalyst, noble metals, and bimetallic alloy catalysts. In contrast to previous studies, we have recently reported that supported rhenium nanoparticles are highly active, selective, sulfur-tolerant catalysts for the HDO of pyrolysis oil derived phenolic compounds. In this presentation, we will discuss how the structure and activity of rhenium catalyst can be altered by the support properties and metal promoters. We also discuss the challenges for the HDO of real pyrolysis oils in a continuous flow reactor. |
