Systems and processes of providing novel thermal energy sources for hydrothermal liquefaction (HTL) reactors are described herein. According to various implementations, the systems and processes use concentrated solar thermal energy from a focused high-energy beam to provide sufficient energy for driving the HTL biomass-to-biocrude process. In addition, other implementations convert biowaste, such as municipal biosolids and grease and food waste, to biocrude using anaerobic digesters, and a portion of the biogas generated by the digesters is used to produce the thermal and/or electrical energy used in the HTL reactor for the biomass-to-biocrude process. Furthermore, alternative implementations may include a hybrid system that uses biogas and solar radiation to provide sufficient thermal energy for the HTL reactor.

A method for converting hydrocarbon materials into a product includes receiving a hydrocarbon feedstock in a first reaction chamber, receiving a process gas in the first reaction chamber, and forming a first set of discharge conditions in the presence of energy from a microwave generator, in the first reaction chamber, to convert the hydrocarbon feedstock into an intermediate product for delivery to a second reaction chamber. The method also includes delivering the intermediate product to the second reaction chamber, forming a second set of discharge conditions, and converting the intermediate product into a final product in the second reaction chamber.

Products from a high pressure processing system are separated and purified. The processing system is adapted for pressurizing and heating a feed mixture comprising carbonaceous material(-s) in the presence of homogeneous catalysts and liquid organic compounds to produce a converted feed mixture. The converted feed mixture is cooled and depressurized, and then separated into: a gas phase, an oil phase, and a water phase comprising liquid organic compounds and dissolved homogeneous catalysts comprising potassium and/or sodium. The liquid organic compounds and dissolved homogenous catalysts are at least partly recovered from said water phase, thereby producing a first water phase stream enriched in liquid organic compounds and homogeneous catalysts and a second water phase stream depleted in liquid organic compounds and homogeneous catalysts. The first water phase is at least partly recycled to the feed mixture, with a bleed stream being withdrawn therefrom prior to recycling.

There is a process for the production of a liquid fuel and of a gaseous fuel from biomass. The biomass is sent to a pre-treatment section to form a homogeneous phase that can be moved and/or pumped, wherein inert parts are separated from the biomass and the biomass shredded and/or ground to reduce its size. The homogeneous phase obtained is then subjected to subcritical hydrothermal liquefaction at a temperature between 240 C. and 310 C. to form a liquefied phase. The liquefied phase is separated. After separation, the process continues in two alternative and mutually exclusive modes. In the first mode, the first aqueous phase is subjected to an anaerobic reaction with multiple stages producing biogas; the oily phase is separated into a bio-oil and a solid residue. In the second mode, the separate mixed phase is separated by density or dynamics forming a first aqueous phase, bio-oil and a gaseous phase. The first aqueous phase is subjected to a multiple-stage anaerobic reaction from which biogas, a muddy current and a second aqueous phase are produced.
