  • Patent number: 11357183
    Abstract: Pelagic, surface floating, macroalga, Sargassum is harvested at large scale from a free-roaming farm floating freely on the ocean surface, monitored and tracked with GPS drifters and contained only by naturally occurring circular currents known as eddies or gyres, without aquaculture equipment. The farming technique occurs in open ocean through the utilization of system design and technology. Satellite imagery is interpreted to locate naturally occurring Sargassum aggregations or mats. Harvest vessel(s) travel to an identified mat, where only a portion of the natural mat is harvested as starter culture for a free-roaming farm. Cuttings are left behind to become new plants to restore the “mother mat” for no net loss of habitat and for migration for cohabitating organisms. The remainder of the biomass is transported to the identified free-roaming farm site which is in a suitable Eddie. GPS drifters are adhered with seedlings until the crop is ready for harvest.

  • Patent number: 11253895
    Abstract: Systems and methods for treating contaminated soil and groundwater are contemplated. An aqueous slurry may be formulated from particles of solid-phase organic materials having particle sizes between 0.1 and 100 microns, which serve as organic electron donors which may biodegrade subsurface contaminants. The aqueous slurry is injected into an environmental subsurface at a pressure lower than the fracture pressure of the subsurface, which will result in a more uniform distribution of the slurry throughout the subsurface, rather than concentrated deposition of the solid-phase organic materials at points along the fractures, and will also tend to reduce disruption of the architecture of the soil matrix, increasing the utility of the remediated soil and preventing an increase in the rates of generation and efflux of methane and nitrous oxide from the soil to the atmosphere.

  • Patent number: 11052372
    Abstract: A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.

  • Patent number: 10167436
    Abstract: Example embodiments provide methods and apparatuses for providing fuel briquettes from human feces. In an example embodiment, feces are treated to inactivate pathogens resident therein and to cause the cellulose material in the feces to undergo a phase transition. The treatment of the feces comprises heating the feces. Briquettes are formed from a mixture comprising the treated feces and carbonized agricultural waste product. The treated feces acts a binder such that the mixture may be formed into briquettes.

  • Patent number: 10150934
    Abstract: In a process for purifying fatty acid alkyl esters, particularly methyl and ethyl esters, by means of vacuum distillation in a distillation column, water or steam is introduced into the distillation column and, during distillation, brought into contact with the fatty acid alkyl esters in the gas phase. This results in a significant reduction in the sulphur content and in the acid number of the fatty acid alkyl ester.

  • Patent number: 10092890
    Abstract: Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, to produce ethanol and/or butanol, e.g., by fermentation.

  • Patent number: 10023809
    Abstract: This disclosure provides a new approach for bio-oil upgrading using methane as reductant instead of hydrogen. Guaiacol, produced by thermal degradation of lignin, represents a model compound for upgrading of fast pyrolysis bio-oils by deoxygenation. To overcome the high cost of H2, methane is used to deoxygenate guaiacol. On Pt/C catalyst, in terms of guaiacol conversion and product distribution, methane is found to exhibit comparable deoxygenation performance as H2. Its lifetime, however, is lower (<3 hrs). In one embodiment, the lifetime of Pt—Bi/C catalyst is extended by addition of bismuth as a promoter.
