  • Patent number: 8816144
    Abstract: Multistage processing of biomass to produce at least two separate fungible fuel streams, one dominated by gasoline boiling-point range liquids and the other by diesel boiling-point range liquids. The processing involves hydrotreating the biomass to produce a hydrotreatment product including a deoxygenated hydrocarbon product of gasoline and diesel boiling materials, followed by separating each of the gasoline and diesel boiling materials from the hydrotreatment product and each other.

  • Patent number: 8809606
    Abstract: Methods and apparatus for 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 are disclosed. In particular, multi-stage processes are disclosed to convert 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. Disclosed processes subject 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. Also disclosed are apparatus for performing multi-stage processes of converting waste products into useful materials, and at least one oil product that arises from the process.

  • Patent number: 8708383
    Abstract: The bucket lifting assembly is for use in lifting and transporting a bucket of no particular size via a fork of a forklift. The bucket lifting assembly is configured to attach onto opposing side handles of a bucket in order to lift and transport said bucket. The bucket lifting assembly is comprised of a lateral member that connects with vertical members that extend downwardly and engage opposing side handles of the bucket. The vertical members are able to slide laterally with respect to the lateral member so as to adjust for different bucket sizes. The lateral member includes a fort securing member that is affixed from underneath the lateral member such that a forklift fork is inserted and secured there between in order to prevent unintended separation when in use.

  • Publication number: 20130035528
    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: 8335775
    Abstract: Techniques are provided for managing file versions. In one technique, versions of directories are created responsive to creation of versions of files descendant from the directories. Directory versions are associated with times. Interfile links are maintained so file versions descendant from a directory version reflect the directory version's time. In another technique, a mechanism is provided for tagging file versions that shouldn't be overwritten. Responsive to a first file version's update, it is determined whether that version is tagged. If so, a second version is stored while retaining the first version. Otherwise, the first version is deleted responsive to the second version's storage. In another technique, responsive to a first file version's change, it is determined whether first criteria are satisfied. If so, a second version is created while retaining the first version, and versions of the file's ancestor files that satisfy second criteria are created.

  • Patent number: 8329876
    Abstract: The invention provides reagents and methods for conjugating a polymer specifically to the ?-amine of a polypeptide. The invention provides monofunctional, bifunctional, and multifunctional PEGs and related polymers having a terminal thioester moiety capable of specifically conjugating to the ?-amine of a polypeptide having a cysteine or histidine residue at the N-terminus. The invention provides reactive thioester-terminated PEG polymers that have suitable reactivity with an N-terminal cysteine or histidine residue of a polypeptide to produce an amide bond between the PEG molecule and the polypeptide.

  • Publication number: 20120260563
    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.
