Abstract: Methods for obtaining a biocrude intermediate by hydrothermal liquefaction of plant wastes are provided. Using a waste feed having a high cellulose content, the method involves grinding the waste feed to obtain a pulverized waste feed, and subjecting the pulverized waste feed to hydrothermal liquefaction at a temperature at or greater than at about 250° C. At this temperature or greater a catalyst is not necessary to obtain the biocrude. A lower temperature can be used, such as greater than about 150° C. in presence of a catalyst. The step of grinding the plant material, for example ball grinding, reduces particle size and crystallinity, and combined with the high temperature treatment improves the yield of biocrude. Biocrude can be upgraded to biofuel by high temperature hydrodeoxygenating in the presence of hydrogen. Plant wastes that would otherwise contribute green house gases are instead converted to fuels.

Abstract: A waste stream of organic matter such as sewage, plant and plastic matter is received for recycling and treated with high temperature and pressure to generate useful organic products such as bio-oil and gas. Byproducts such as char and an aqueous phase including water can be selectively recycled or beingly discarded. An oxidant added to a reactor containing waste from the waste stream facilitates an autothermal reaction under the temperature and pressure applied to the reactor, boosting the temperature slightly from the reactions therein. The reactor generates useful hydrocarbons such as bio-oil resulting from disruption of organic bonds. A combination of oxidation and radical initiation results from the oxidant, and provides an increased yield of bio-oil while decreasing char when compared to temperature and pressure alone. A stoichiometric quantity of the oxidant limits complete conversion of carbon into carbon dioxide by limiting available oxygen and therefore favoring hydrocarbon formation.

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.
