Abstract: A recycling and waste management process receives municipal solid waste (MSW) with substantial organic content to form a self-sustaining Hydrothermal Mineralization (HTM) process based on Supercritical Water Oxidation (SCWO) to receive supercritical steam and carbon dioxide with potential for electrical generation before forming calcium carbonate suitable for concrete production. Hydrothermal mineralization (HTM) provides a rapid elimination of organic wastes while simultaneously producing a non-emissive and thermally stable cement additive to act as a carbon sink. Hydrothermal mineralization (HTM) provides a rapid disposal pathway for organic wastes, a green source of electricity and a final product that can be coupled with traditional and alternative cement productions to reduce carbon footprints of cement production.

Abstract: Catalyst composition and parameters for catalytic hydrothermal liquefaction of biomass to bio-oil fuels target municipal solid waste (MSW) rather than lignin rich plant waste typically sought for bio-oil production. An HTL (Hydrothermal Liquefaction) reactor generates bio-fuel from municipal solid waste (MSW), including receiving, in the HTL reactor, non-lignin based waste from a municipal processing stream, and adding a solvent for extracting sugars from green waste components of the municipal processing stream. The reactor extracts a liquid from the received waste, and converts water soluble products in the liquid into oil soluble products via C—C (carbon-to-carbon) coupling reactions. A catalyst added to the resulting aqueous stream recovers a beneficial oil product, and is optimized by tuning acid and base sites on the solid catalyst.

Abstract: A petroleum refining method for upgrading petroleum products improves the efficiency and reduces the costs of upgrading oils, such as lipids, bitumen, crude oil, fracking oils, synthetic oils, and other feeds, to produce useful fuels and chemical precursor streams. Usage of a specific type of zeolite (ZSM-5) catalyst, supercritical water to control coke formation, and a specific response to phase behavior and other catalytic effects optimize the process. A prescribed set of reactor conditions employing supercritical water increases activity of the catalyst in industrial reactions.
