Attrition resistant hardened zeolite materials for air filtration media

Номер: US20120118160A1

Автор: Fitzgerald A. Sinclair, Michael C. Withiam, Ruth G. Heffes, Terry W. Nassivera

Принадлежит: JM Huber Corp

Environmental control in air handling systems that are required to provide highly effective filtration of noxious gases particularly within filter canisters that are ultrasonically welded enclosures is provided. In one embodiment, a filtration system utilizes a novel zeolite material that has been hardened to withstand ultrasonic welding conditions in order to reduce the propensity of such a material to destabilize and/or dust. Such a hardened zeolite thus enables for trapping and removal of certain undesirable gases (such as ammonia, ethylene oxide, formaldehyde, and nitrous oxide, as examples) from an enclosed environment, particularly in combination with metal-doped silica gel materials. Such a hardened zeolite is acidic in nature and not reacted with any salts or like substances and, as it remains in a hardened state upon inclusion within a welded filter device, the filter medium itself permits proper throughput with little to no dusting, thereby providing proper utilization and reliability for such a gas removal purpose. Methods of using and the application within specific filter apparatuses are also encompassed within this invention.

Disclosed is a novel adsorbent for use in a 99 Mo/ 99m Tc generator, which is a medical diagnostic radioisotope generator, and in a 188 W/ 188 Re generator, which is a therapeutic radioisotope generator. The adsorbent composed of sulfated alumina or alumina-sulfated zirconia exhibits adsorption capacity superior to that of conventional adsorbents, and is stable and is thus loaded in a dry state in an adsorption column so that the radioisotope 99 Mo or 188 W can be adsorbed. Thus, it is possible to miniaturize the column, and such a miniaturized column is small, convenient to use, and highly efficient, and extracts a radioisotope satisfying the requirements for pharmaceuticals, and thus can be useful for radioisotope generators extracting 99m Tc or 188 Re.

Until an engine post-initiation catalyst is activated, the amounts of a high-boiling-point hydrocarbon and an unsaturated hydrocarbon that are contained in the exhaust gas flowing into the catalyst are reduced so that the NO x -adsorbing activity cannot be deteriorated by the adhesion activity of the hydrocarbons while maintaining the CO concentration in the exhaust gas flowing into the catalyst at a level higher than the concentration required for the adsorption of NO x .

Catalytic adsorbents obtained from municipal sludges, industrial sludges, compost and tobacco waste and process for their production

Номер: US20130102456A1

Автор: Teresa J. Bandosz

Принадлежит: Research Foundation Of City University of New York

Industrial waste derived adsorbents were obtained by pyrolysis of sewage sludge, metal sludge, waste oil sludge and tobacco waste in some combination. The materials were used as media to remove hydrogen sulfide at room temperature in the presence of moisture. The initial and exhausted adsorbents after the breakthrough tests were characterized using sorption of nitrogen, thermal analysis, XRD, ICP, and surface pH measurements. Mixing tobacco and sludges result in a strong synergy enhancing the catalytic properties of adsorbents. During pyrolysis new mineral phases are formed as a result of solid state reaction between the components of the sludges. High temperature of pyrolysis is beneficial for the adsorbents due to the enhanced activation of carbonaceous phase and chemical stabilization of inorganic phase. Samples obtained at low temperature are sensitive to water, which deactivates their catalytic centers.

Rising global temperatures could lead to many disasters including severe weather events, drought and flooding, and thus food supply shortfalls, lack of water security, deterioration of ecosystems, and spread of vector-borne diseases.The main greenhouse gases associated with climate changes are carbon dioxide, methane, nitrous oxide and some halogenated compounds. The quantity of COemitted to the atmosphere due to human activities is much greater than those of other greenhouse gases. As a result, COmakes the greatest contribution to the greenhouse effect despite its low unit globe warming potential.

The invention relates to a mixed salt composition which is useful as a CO 2 sorbent. The mixed salt composition comprises a Mg salt, and at least one Group IA element salt, where the Mg and Group IA element are present at a molar ratio of from 3:1 to 8:1. The resulting composition can adsorb about 20% or more of CO2 in a gas. Via varying the molar ratios of the components, and the Group IA element, one can develop compositions which show optional functionality at different conditions. The composition is especially useful in the adsorptive capture of CO 2 on mobile sources, such as transportation vehicles, where it can be recovered during regeneration of the adsorbent composition and the CO 2 used as a coolant gas, as a reactant in manufacture of fuel, and so forth.

System and Method for Carbon Dioxide Capture and Sequestration

Номер: US20140010719A1

Автор: Peter Eisenberger

Принадлежит: Individual

A method and a system for removing carbon dioxide directly from ambient air, using a sorbent under ambient conditions, to obtain relatively pure CO 2 . The CO 2 is removed from the sorbent using process heat, preferably in the form of steam, at a temperature in the range of not greater than about 130° C., to capture the relatively pure CO 2 . Increased efficiency can be achieved by admixing with the ambient air, prior to contacting the sorbent, a minor amount of a preferably pretreated effluent gas containing a higher concentration of carbon dioxide. The captured carbon dioxide can be stored for further use, or sequestered permanently. The system provides the sorbent substrate and equipment for carrying out the above method, and for obtaining purified carbon dioxide for further use in agriculture and chemical processes, or for permanent sequestration.

Принадлежит: Clariant Produkte(Deutschland)GmbH

The present invention relates to a heat exchanger module with thermal management containing a titano-alumino-phosphate as adsorber, which displays a high hydrothermal stability and already desorbs the adsorbed water again under the action of low heat. By targeted action of temperature, the adsorbed water is condensed out, whereby heat energy is released. By means of the action of low heat, the condensed water can be adsorbed again as cold vapour on the adsorber, whereby heat energy is released. The heat exchanger module can be used to heat objects, appliances or rooms on the basis of the adsorption energy being released during the adsorption, as this is discharged and used further. In addition to heating, the cooling of rooms, objects and appliances is also possible, as the area surrounding the heat exchanger module is cooled due to a fall in the temperature in the heat exchanger module. 122-.
