Systems and methods for converting biomass to biocrude via hydrothermal liquefaction

A process of converting biomass feedstock to biocrude comprising:

• combusting biogas, by a hydrothermal liquefaction system, to produce thermal energy;
• pumping biomass feedstock through a hydrothermal liquefaction reactor of the hydrothermal liquefaction system;
• and
• heating, in the hydrothermal liquefaction reactor, the biomass feedstock using the thermal energy from the combustion of the biogas.

A process of converting biomass to biocrude, comprising:

• feeding municipal sludge to at least one anaerobic digester, the municipal sludge comprising biowaste;
• collecting thermal energy from combustion of a first portion of biogas generated from partial digestion of the biowaste;
• providing the thermal energy from combustion of the first portion of biogas to a generator;
• providing a second portion of biogas generated from partial digestion of the biowaste to a hydrothermal liquefaction system for combusting, the hydrothermal liquefaction system comprising a hydrothermal liquefaction reactor;
• providing the thermal energy from combustion of the second portion of the biogas, waste heat generated by the generator, at least a portion of electrical energy generated by the generator, and the partially digested biowaste from the anaerobic digester to the hydrothermal liquefaction reactor;
• recirculating waste heat generated by the hydrothermal liquefaction system to the anaerobic digesters;
• and
• harvesting biocrude from the hydrothermal liquefaction system.
