Upgrading of Hydrothermal Liquefaction Biocrude from Forest Residues Using Solvents and Mild Hydrotreating for Use as Co-processing Feed in a Refinery

The presence of a variety of reactive oxygen compounds in biocrudes derived from thermochemical conversion of biomass creates challenges for their co-processing with petroleum in a refinery. In this work, we explore two different technology approaches to
