Abstract: A method can include: in a heat exchanger, cooling a biocrude oil emulsion stream received from a biocrude oil emulsion source, wherein the emulsion can include a biocrude oil phase, an aqueous phase, and solids; in a first mixing vessel, mixing the emulsion with a solvent to dissolve the biocrude oil phase and form a biocrude-solvent solution; in a first separator assembly, separating the biocrude-solvent solution from the aqueous phase and the solids; in a solvent recovery apparatus, recovering solvent from the biocrude-solvent solution; in a second mixing vessel, mixing the solvent with the aqueous phase and the solids received from the first separator assembly to dissolve biocrude oil remaining in the aqueous phase and the solids; and supplying the solvent and biocrude oil to the first mixing vessel as the solvent. In some examples, such a method can more effectively separate biocrude oil from the emulsion than conventional techniques.

Abstract: A process where a liquid or supercritical CO2 co-solvent is used in a hydrothermal liquefaction (HTL) process. The process improves yield of the HTL process.

Abstract: Disclosed herein are embodiments of a system and method that combine carbon dioxide reduction and methanol oxidation to provide an efficient path to formaldehyde production. The system and method embodiments are designed to rely on methanol oxidation to formaldehyde to provide the electrons needed to drive carbon dioxide reduction to carbon monoxide. The carbon monoxide obtained by carbon dioxide reduction is converted to the methanol used in the system/method via hydrogenation.

Abstract: A method, system and apparatus for estimating automobile damage susceptible of paintless dent repair (P.D.R.). The method includes characterizing damage susceptible of P.D.R. by inspection of the vehicle; communicating those characterizations to a central computer, processing the characterizations based on predetermined rules stored in the central computer, and generating a report including a estimation of repair costs for the vehicle. The communication can be over a global computer network, a WAN, a LAN, or other ways to communicate between remote and central devices. A template can be used to assist in the characterization of damage.
