Abstract
Biomass based feeds are processed under hydrothermal treatment conditions to produce a hydrocarbon liquid product and a solids portion. The hydrothermal treatment is performed in the presence of catalyst particles. The presence of the heterogeneous catalyst can modify the nature of the hydrocarbon products produced from the hydrothermal treatment. After the hydrothermal treatment, the catalyst particles can be separated from the algae-based solids, to allow for recycle of the catalyst particles.
