Title: A Review and Perspective of Recent Bio-Oil Hydrotreating Research

The pathway for catalytic hydrodeoxygenation of biomass derived fast pyrolysis oil represents a compelling route for production of liquid transportation fuels. There has been continued progress and advancements in both the public and private research areas towards driving this technology to completion. Published research and patent literature have demonstrated that continued development of HDO as a part of a processes for production liquid transportation using biomass is being advanced for both fuel blend stocks and for refinery intermediates for co-processing. Much of the research has still focused on “quality” metrics around single or groups of unit operations generating partially treated bio-oil streams without assessing upstream and downstream implications. However, there is an encouraging amount of research that is now being targeted and assessed with attempts to understand the impact on the final fuel product, regardless of the route. Much of the most important research is moving towards continuous, industrially relevant processes where data can be generated to adequately inform process and economic modeling. As the technology for producing liquid transportation fuels from pyrolysis/HDO/coprocessing is driving towards commercialization, further research should be prioritized on the basis of impact to a techno-economic analyses.
