  • Patent number: 10977275
    Abstract: Methods and systems for synchronizing distributed databases are provided. In one aspect, a method includes transmitting a request to determine a schema of a first database and updating a metadata store with the schema. The method includes generating at least one database query. The method includes, responsive to the database query, selectively determining a data block size for a second database; segmenting a data source stored in the second database into sink data blocks; processing the data source into sink hashes; and transmitting, to an agent, at least one selected sink hash, wherein the agent transmits instructions to segment a table associated with the first database into source data blocks; process the table into source hashes; and generate, in response to a determination that the at least one selected sink hash differs from a corresponding source hash, query results. The method includes updating the data source with the query results.

  • Publication number: 20210055167
    Abstract: An improved ultrasonic waveguide for an ultrasonic thermometry system is provided. The waveguide includes a series of sensing zones, each of which is tuned to a specific narrow frequency band. The waveguide is acoustically coupled to a transducer, which launches a longitudinal elastic wave of desired waveform and frequency. The wave propagates down the waveguide, and is reflected from the sensing zone that is tuned to that frequency. Each sensing zone is designed to be highly reflective to a narrow frequency band while being transparent to other frequencies.

  • Patent number: 10647933
    Abstract: Hydropyrolysis processes that accompany the generation of activated carbon as an end product, as well as processes for the production of activated carbon from hydropyrolysis char, are described. Representative processes comprise upgrading, by steam activation, char that is formed from solid biomass-containing feedstocks and/or solid biomass derived feedstocks, such as lignocellulosic feedstocks (e.g., wood). Such processes are associated with a number of advantages in terms of achieving operating synergies, obtaining desirable intermediate material and end product properties, reducing environmental impact, and significantly improving economic attractiveness.

  • Patent number: 10619105
    Abstract: Various techniques are disclosed for pretreating municipal solid waste (MSW) and other biomass-containing feedstocks that may be of a poorer quality and consequently more difficult, or even impossible, to convert to higher value liquid products (e.g., transportation fuels) using conventional processes. Such conventional processes may otherwise be satisfactory for the conversion of the biomass portion of the feedstock alone. The pretreatment of biomass-containing feedstocks may generally include steps carried out prior to a hydropyrolysis step and optionally further steps, in order to change one or more characteristics of the feedstock, rendering it more easily upgradable.

  • Patent number: 10392566
    Abstract: Hydropyrolysis processes are described, in which differing types of feedstocks, including at least one biorenewable feedstock, namely a biomass-containing feedstock, may be co-processed to allow enhancements in operating conditions and/or product properties, depending on changing customer requirements and/or overall market demands. According to specific embodiments, an aliphatic hydrocarbon precursor or an aromatic hydrocarbon precursor is co-processed with the biomass-containing feedstock to enhance an operating condition (e.g., a reactor temperature profile) of the hydropyrolysis process and/or a property (e.g., cetane number) of a liquid product (e.g., a diesel boiling range fraction) obtained from a substantially fully deoxygenated hydrocarbon liquid.

  • Patent number: 9938466
    Abstract: A hydropyrolysis process comprises feeding both (i) hydrogen and (ii) a biomass-containing feedstock or a biomass-derived feedstock, to a hydropyrolysis reactor vessel. The process comprises producing a CO2-containing vapor stream and at least one liquid product. A CO2 product, separated from the CO2-containing vapor stream, is advantageously used for at least one inertization function of the hydropyrolysis process. Representative inertization functions include operation of solids transport equipment, blanketing of liquid containers, drying of biomass-containing feedstock or biomass-derived feedstock, conveying or separating solids, and combinations thereof. Importantly, CO2 products utilized for these inertization functions may be obtained predominantly, if not completely (depending on the nature of the feedstock), from renewable carbon in biomass.

  • Patent number: 9593282
    Abstract: A system and method for processing biomass into hydrocarbon fuels that includes processing a biomass in a hydropyrolysis reactor resulting in hydrocarbon fuels and a process vapor stream and cooling the process vapor stream to a condensation temperature resulting in an aqueous stream. The aqueous stream is sent to a catalytic reactor where it is oxidized to obtain a product stream containing ammonia and ammonium sulfate. A resulting cooled product vapor stream includes non-condensable process vapors comprising H2, CH4, CO, CO2, ammonia and hydrogen sulfide.

  • Patent number: 9512364
    Abstract: This invention relates to a process for thermochemically transforming biomass or other oxygenated feedstocks into high quality liquid hydrocarbon fuels. In particular, a catalytic hydropyrolysis reactor, containing a deep bed of fluidized catalyst particles is utilized to accept particles of biomass or other oxygenated feedstocks that are significantly smaller than the particles of catalyst in the fluidized bed. The reactor features an insert or other structure disposed within the reactor vessel that inhibits slugging of the bed and thereby minimizes attrition of the catalyst. Within the bed, the biomass feedstock is converted into a vapor-phase product, containing hydrocarbon molecules and other process vapors, and an entrained solid char product, which is separated from the vapor stream after the vapor stream has been exhausted from the top of the reactor.

  • Patent number: 9436257
    Abstract: A system includes power supply units (PSUs) to supply power to components. For each PSU, a power conversion efficiency profile is determined. A maximum amount of power consumed during operation of the components is determined. A minimum number of PSUs capable of providing the maximum amount of power is determined. A first amount of power consumed at inputs of the minimum number of PSUs is calculated based on the maximum amount of power and based on the determined power conversion efficiency profile of each of the PSUs. A first number of PSUs to engage is determined, the first number greater than the minimum number of PSUs, wherein a total amount of power consumed at inputs of the first number of PSUs during operation of the system is less than the first amount of power, the determining based on the power conversion efficiency profile of each PSU.

  • Publication number: 20150060258
    Abstract: The present invention addresses the processing of waste and low-value products to produce useful materials in reliable purities and compositions, at acceptable cost, without producing malodorous emissions, and with high energy efficiency. In particular, the invention comprises a multi-stage process that converts various feedstocks such as offal, animal manures, municipal sewage sludge, tires, and plastics, that otherwise have little commercial value, to useful materials including gas, oil, specialty chemicals, and carbon solids. The process subjects the feedstock to heat and pressure, separates out various components, then further applies heat and pressure to one or more of those components. Various materials produced at different points in the process may be recycled and used to play other roles within the process. The invention further comprises an apparatus for performing a multi-stage process of converting waste products into useful materials, and at least one oil product that arises from the process.
