Patent number: 8288307Abstract: A hydrogenation catalyst including a base material coated with a catalytic metal is made using mechanical milling techniques. The hydrogenation catalysts are used as an excellent catalyst for the dehalogenation of contaminated compounds and the remediation of other industrial compounds. Preferably, the hydrogenation catalyst is a bimetallic particle including zero-valent metal particles coated with a catalytic material. The mechanical milling technique is simpler and cheaper than previously used methods for producing hydrogenation catalysts.Type: GrantFiled: October 21, 2010Date of Patent: October 16, 2012Assignee: The United States of America as Represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Jacqueline W. Quinn, Christian A. Clausen, Cherie L. Geiger, Brian S. Aitken

Patent number: 8163972Abstract: PCBs are removed from contaminated media using a treatment system including zero-valent metal particles and an organic hydrogen donating solvent. The treatment system may include a weak acid in order to eliminate the need for a coating of catalytic noble metal on the zero-valent metal particles. If catalyzed zero-valent metal particles are used, the treatment system may include an organic hydrogen donating solvent that is a non-water solvent. The treatment system may be provided as a “paste-like” system that is preferably applied to natural media and ex-situ structures to eliminate PCBs.Type: GrantFiled: May 13, 2009Date of Patent: April 24, 2012Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Jacqueline W. Quinn, Christian A. Clausen, Cherie L. Geiger, Kathleen B. Brooks

Patent number: 8062442Abstract: 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.Type: GrantFiled: April 3, 2007Date of Patent: November 22, 2011Assignee: University of Central Florida Research Foundation, Inc.Inventors: Christian Clausen, III, Cherie L. Geiger, Michael Sigman, Rebecca Fidler

Patent number: 7582682Abstract: Emulsified systems of a surfactant-stabilized, biodegradable water-in-solvent emulsion with bimetallic particles contained with the emulsion droplets are useful at removing PCBs from ex situ structures. The hydrophobic emulsion system draws PCBs through the solvent/surfactant membrane. Once inside the membrane, the PCBs diffuse into the bimetallic particles and undergo degradation. The PCBs continue to enter, diffuse, degrade, and biphenyl will exit the particle maintaining a concentration gradient across the membrane and maintaining a driving force of the reaction.Type: GrantFiled: August 15, 2007Date of Patent: September 1, 2009Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Jacqueline W.
