  • Patent number: 10807076
    Abstract: This application discloses a mesoporous catalyst formed by combining a matrix precursor treated with a polyphosphate, and a metallic oxide treated with a cationic electrolyte. The combined treatment with the polyphosphate and cationic polyelectrolyte yields unexpected improvements in attrition resistance, while maintaining high overall pore volume, even as the ratio of meso pore volume to macro pore volume of the formed FCC catalyst increases.
    Type: Grant

  • Patent number: 9244045
    Abstract: In one embodiment, a system and a method for identifying the class of a component of a mixture includes collecting samples from a sample source, determining a summed ion spectrum for each sample and generating sample data from the summed ion spectra, comparing the sample data with reference summed ion spectra of multiple reference substances to determine correlations between the reference substances and the sample data, and evaluating the correlations of the substances of each substance class to determine which substance class most closely correlates to the sample data.

  • Patent number: 8721813
    Abstract: Bimetallic alloys prepared in a ball milling process, such as iron nickel (FeNi), iron palladium (FePd), and magnesium palladium (MgPd) provide in situ catalyst system for remediating and degrading nitro explosive compounds. Specifically, munitions, such as, 2,4,6-trinitrotoluene (TNT), cyclo-1,3,5-trimethylene-2,4,6-trinitramine (RDX), nitrocellulose and nitroglycerine that have become contaminants in groundwater, soil, and other structures are treated on site to remediate explosive contamination.

  • Patent number: 8062442
    Abstract: Triacetone triperoxide (TATP) and other explosives of the peroxide family are safely degraded in situ. Nano and micron size metal particles in an elemental state include pure iron and magnesium or iron and magnesium particles that are mechanically alloyed with palladium and nickel. The metal particles are used in both the elemental state and in emulsions that are made from water, a hydrophobic solvent, such as corn oil, and a food-grade nonionic surfactant. The neat metals and emulsified zero valent metals (EZVM) safely degrade TATP with the major degradation product being acetone. The EZVM system absorbs and dissolves the TATP into the emulsion droplets where TATP degradation occurs. EZVM systems are ideal for degrading dry TATP crystals that may be present on a carpet or door entrance. Both the neat metal system and the emulsion system (EZVM) degrade TATP in an aqueous slurry.

  • Patent number: 7755041
    Abstract: A triacetone triperoxide cloud associated with a triacetone triperoxide explosive attached to a hard target is remotely detected by operating differential-absorption lidar lasers to transmit a laser beam toward the hard target at differing wavelengths. A backscattered laser beam reflected from the lidar target (hard target, person, aerosols, clouds, buildings) is detected because a cloud of triacetone triperoxide in front of the lidar target and between the lidar target and the differential-absorption lidar system produces a differential-absorption signal having characteristics that identify the triacetone triperoxide. In a second embodiment, a triacetone triperoxide cloud that is absorbing optical radiation from its ambient environment and which is attached to a hard target is detected from a location remote from the triacetone triperoxide explosive by detecting an optical radiation absorption signature characterized by triacetone triperoxide absorption lines.

  • Patent number: 7691234
    Abstract: The present invention relates to an aqueous composition comprising anionic organic polymeric particles and colloidal anionic silica-based particles. The anionic organic polymeric particles are obtainable by polymerizing one or more ethylenically unsaturated monomers together with one or more polyfunctional branching agents and/or polyfunctional crosslinking agents. The anionic organic polymeric particles and the colloidal anionic silica-based particles in the aqueous composition are present in an amount of at least 0.01% by weight based on the total weight of the aqueous composition. The present invention further relates to a method for the preparation of the aqueous composition, uses of the aqueous composition and a process for the production or paper, in which the aqueous composition is added to a cellulosic suspension.

  • Publication number: 20050016387
    Abstract: Rib-O-Wheel for a gas fired Bar-B-Cue rotisserie. The Rib-O-Wheel comprises four hanging baskets and two basket attachment end wheels constructed from stainless steel or high tensile steel coated with chrome or a porcelain finish. The basket attachment end wheels slide onto any standard 1/4 in. rotisserie bar and are secured in place by a thumb screw. The baskets are placed between the basket attachment end wheels and are hung on fixed pins. The baskets rotate around the attachment end point pins as the rotisserie rotates around its center axis.
