Patent number: 10175213Abstract: Methods and devices for directly measuring the degree of saturation or degree of deactivation of an adsorbent and/or catalytic bed are described herein. The devices contain an inlet, an outlet, a catalytic and/or adsorbent bed, and optionally a support bed for supporting the catalytic and/or adsorbent bed. The devices further contain one or more structures attached to the reactor that allow for insertion of one or more sensors into the reactor. The sensor is used to spectroscopically interrogate the adsorbent and/or catalyst in situ, providing real-time information regarding adsorbant saturation and/or catalyst deactivation. The devices and methods described herein can be used to determine the saturation degree of adsorbent materials or catalyst beds that are involved in gas-liquid and liquid-liquid heterogeneous systems, such as those used in scrubbing and extraction.Type: GrantFiled: January 31, 2013Date of Patent: January 8, 2019Assignee: INTRAMICRON, INC.Inventors: Paul S.

Patent number: 9964355Abstract: Improved methods for preparing highly porous mesh media and loading functional particles into the media are described herein. The highly porous media can be used as supports for catalyst materials for a variety of applications, such as desulfurization. Pre-manufactured catalyst can be loaded into the sintered open media. Thus, the contamination issues associated wetlay paper making and pre-oxidation, the deactivation issues associated with the sintering and pre-oxidation steps, and the corrosion issues associated with the catalyst formation step can be avoided. The methods described herein result in the formation of highly porous media with functional particles immobilized inside.Type: GrantFiled: March 13, 2013Date of Patent: May 8, 2018Assignee: IntraMicron, Inc.Inventors: Hongyun Yang, Paul S.

Patent number: 7501012Abstract: A microfibrous matrix with embedded supporting particulates/fibers and chemically reactive materials is provided as a filtration system for the removal of contaminants and other harmful agents from liquid and gaseous streams. Such materials may include chemically reactive materials as high surface area carbons, zeolites, silicas, aluminas, inorganic metal oxides, polymer resins, ZnO, ZnO/Carbon, Pt/?-Al2O3, PtCo/?-Al2O3, ZnO/SiO2 and various other catalysts, sorbents or reactants. The invention may be used to protect the intolerant anodes and cathodes of fuel cells from damaging H2S while simultaneously aiding the selective conversion of CO to CO2 in fuel streams predominated by hydrogen, to provide a highly efficient gas and/or liquid separation and purification methodology for gas masks, building filtration systems, and/or as polishing media located downstream of traditional packed bed filtration systems.Type: GrantFiled: August 26, 2004Date of Patent: March 10, 2009Assignee: Auburn UniversityInventors: Bruce J.

Patent number: 5304330Abstract: A new class of composites results from a matrix of fibers, such as fibers of carbon, alumina, ceramics, and aluminosilicates, interwined in a network of fused metal fibers. The composites can be fabricated to have varying surface area, void volume, and pore size while maintaining high electrical conductivity. Composites are readily prepared from a preform of a dispersion of the metal fibers, other fibers, and an organic binder such as cellulose, by heating the preform at a temperature sufficient to fuse the metal fibers and to volatilize at least 90% of the binder. Where a carbon fiber is used, the metal fibers are fused at a temperature causing a loss of less than about 25%, and usually under 15%, by weight of carbon fiber.Type: GrantFiled: August 21, 1991Date of Patent: April 19, 1994Assignee: Auburn UniversityInventors: Bruce J. Tatarchuk, Millard F. Rose, Gopal A. Krishnagopalan, John N. Zabasajja, David A. Kohler

Patent number: 5102745Abstract: A family of composites are characterized as a network of a first fiber and at least a second fiber, where at least the first fibers have a multiplicity of bonded junctions at their point of crossing. The largest class has metals as one or both of the fibers, although the second fiber can be of materials such as carbon, ceramics, and high surface area materials. The composites can be simply prepared and manifest enormous variation in such properties as void volume, pore size, and electrical properties generally.Type: GrantFiled: November 13, 1989Date of Patent: April 7, 1992Assignee: Auburn UniversityInventors: Bruce J.

Method of optimizing composite preparation for electrical properties: maximum capacitance electrodes
Patent number: 5096663Abstract: Composites of a matrix of metal fibers and carbon fibers interlocked in and interwoven among a network of fused metal fibers are inherently capable of displaying a broad range of values of a particular physical property. Where the composite is made by sintering a preform of the fiber network dispersed in a matrix of an organic binder, the value of the physical property of the resulting composite is a function of several independent variabiles which can be controlled during composite fabrication. With particular regard to the capacitance of a stainless steel-carbon fiber electrode, there is described a method of optimizing capacitance during electrode fabrication.Type: GrantFiled: May 29, 1990Date of Patent: March 17, 1992Assignee: Auburn UniversityInventor: Bruce J.

Patent number: 4804527Abstract: A hypergol spill, e.g., hydrazine, is safely rendered harmless by contacting it with a composition comprising cupric oxide on a porous support. Neutralization is achieved by drawing the hydrazine into the pellet pores where a reduction reaction of cupric oxide takes place. The critical consideration is to avoid flashing or spontaneous thermal decomposition of the hydrazine. Heat of reaction is quenched by the heat capacity of the pellet and water dilution.Type: GrantFiled: June 17, 1986Date of Patent: February 14, 1989Assignee: E.C.C. America Inc.Inventors: Bruce J.
