  • Publication number: 20220252530
    Abstract: A system for predicting rare earth elements (REEs) in a feedstock sample includes a measurement instrument that records a measurement for a sample, a processor communicatively coupled to the measuring instrument, and a memory communicatively coupled to the processor and containing machine readable instructions that, when executed by the processor, cause the processor to correlate the measurement series using a model; and predict a presence of one or more rare earth element based at least in part on the correlation. A method for predicting rare earth elements includes measuring feedstock samples via XRF or PGNAA, to generate a measurements of elements of interest with a lower atomic weight than REEs; correlating the measurements with a model; and predicting a presence of one or more rare earth elements based at least in part on the correlation.

  • Patent number: 10667562
    Abstract: The present disclosure provides components useful in heating, particularly heating of an aerosol precursor solution so as to vaporize the solution and form an aerosol. The disclosure particularly provides an electrically conductive, porous carbon heater. The heater may be combined with an aerosol precursor transport element that also is formed of carbon. The heater and transport element may form an atomizer that can be useful in an electronic smoking article, such as in a cartridge that is adapted for attachment to a control body. In some embodiments, the disclosure provides a cartridge of an electronic smoking article, the cartridge being formed substantially completely of carbon.

    Abstract: A method of forming an aligner includes dipping a positive mold of teeth in a liquid material to form a liquid layer and curing the liquid layer to form a shell. The shell may include an inner layer including material from the liquid material and an outer layer including material from another liquid material. Prior to dipping the mold in the liquid material, features may be coupled to the layer. The features may be selected from the group consisting of an archwire, a sensor, and a bracket. The mold includes model teeth and a gingival margin on a base. Dipping may be to a predefined depth. A fluid level of the material is positioned proximate the gingival margin. The fluid level may define the edge of the shell. A set of aligners including at least one aligner having an edge that defines an opening and the edge is as-formed.

  • Patent number: 8277542
    Abstract: The present invention relates to use of carbon-based sorbents such as activated carbon for controlling vapor phase mercury emissions in coal-fired power plant flue gases or waste incineration flue gases. The invention features new methods that improve the performance of carbonaceous sorbents for mercury control compared to the previous methods. One method consists of injecting the sorbent (consisting of at least some carbonaceous material) into the flue gas where the flue gas temperature is at a value above about 1100° F. and below about 2000° F. The invention also consists of injecting the sorbent within or upstream of an economizer section in a coal-fired power boiler. Injecting the sorbent at the locations indicated above, rather than further downstream, provides increased residence time for contact between the flue gas and the sorbent resulting in increased mercury capture, improved sorbent utilization, and improved fly ash properties.

  • Publication number: 20070274886
    Abstract: Disclosed herein are methods for removing and recovering metalloids from gasification systems. Also disclosed are methods for on-line removal of deposited entrained materials from a heat exchanger unit. A method is provided for on-line removal and recovery of deposits from fossil fuel gasification systems to improve plant performance and recover a valuable metalloid. Plant performance will be improved by decreasing impedance to gas flow and decreasing downtime required to clean the gas cooling system by providing an effective method to remove deposits while the gasification system is operating. In the preferred embodiment of the method, the deposits rich in condensed metals and metalloids are captured on heat transfer surfaces within the range of temperatures of about 400° C. to about 600° C., the temperature of the heat transfer surface is cycled causing the deposit to spall from the steel surface, and the deposits are removed from the gasifier without impacting gasifier operation.
