1. A method of producing fuels and chemicals from biomass feedstock comprising the steps of:
(a) mixing biomass feedstock in a feedstock vessel and introducing the biomass feedstock into a hydrothermal liquefaction reactor;
(b) processing a lignocellulose biomass in a biomass treatment unit to obtain a processed lignocellulose biomass and bioliquor and fermenting the processed lignocellulose biomass in a fermenter to obtain ethanol;
(c) introducing the bioliquor stream into the hydrothermal liquefaction reactor comprising the biomass feedstock to obtain a mixture;
(d) subjecting the mixture to hydrothermal liquefaction by adding a transition-metal catalyst to obtain a liquefied product;
(e) collecting the liquefied product in a collection vessel and separating the liquefied product into a gaseous product and a gas-free product stream; and
(f) separating the gas-free product stream into oil stream comprising fuels and chemicals, a solid phase, and an aqueous phase.
