Biomass based feeds are processed under hydrothermal treatment conditions, e.g., to produce a hydrocarbon liquid product and a solids portion. The hydrothermal treatment is performed in the presence of a dissolved catalyst or catalyst precursor. The presence of the dissolved catalyst or catalyst precursor can modify the nature of the hydrocarbon products produced from the hydrothermal treatment. Des alimentations à base de biomasse sont traitées dans des conditions de traitement hydrothermal, par exemple, pour donner un produit liquide hydrocarboné et une fraction de matières solides. Le traitement hydrothermal est effectué en présence d'un catalyseur ou précurseur de catalyseur dissous. La présence du catalyseur ou précurseur de catalyseur dissous peut modifier la nature des produits hydrocarbonés obtenus par le traitement hydrothermal.
