摘要:
Devices and methods for provided both an antimicrobial vapor such as hydrogen peroxide and/or peracetic acid and water vapor in an enclosed or partially enclosed space are described. The device and method provided is for the reduction or elimination of microbes from air and surfaces in contact with air within an enclosed or partially enclosed space using hydrogen peroxide or peracetic acid in the vapor phase and also provide for humidity from water vapor. The device and method are directed towards a release of an antimicrobial vapor and water vapor through a permeable container/barrier containing a matrix into which water and an antimicrobial vapor producing material are absorbed.

An adsorbent composition comprising a nanoscale shell of metal oxide or hydroxide on an organic-templated-boehmite-nanoarchitecture (OTBN) is provided. The nanoscale shell is prepared by impregnating OTBN with a metal or a non-metal ion, followed by in-situ hydrolysis of the deposited ion on the OTBN surface. The thickness of the shell is less than about 3 nm, which is less than the size of OTBN core. The number of layers of the shell is flexible, thereby leading to a multi-layer nanoscale hybrid composition. The adsorbent composition is capable of removing inorganic anions such as fluoride from water, with an increased adsorption capacity.

Provided are encased parallel channel adsorbent contactor apparatus and systems and swing adsorption processes related thereto. Encased parallel channel adsorbent contactors are useful in swing adsorption processes. A plurality of the encased adsorbent contactors are loaded and sealed together in a swing adsorption vessel such that substantially an entire feed stream must pass through the channels of the contactors and not through stray gaseous stream paths between contactors.

A process for producing an oxygen absorbing agent includes treating an alloy with an aqueous solution of an acid or an alkali, the alloy including at least one transition metal selected from the group consisting of manganese, iron, platinum, and copper group metals and at least one metal selected from the group consisting of aluminum, zinc, tin, lead, magnesium, and silicon to elute and remove at least a part of the component; and subjecting the alloy obtained by removing at least a part of the component in the alloy to treatment with an aqueous solution of a salt of an inorganic acid or a salt of an organic acid that can form a salt with the transition metal as the component, to form a metal salt in at least a part of the surface of the alloy.
摘要:
The present invention provides a novel oxygen absorbent composition being capable of realizing an oxygen absorbent not responding to a metal detector, being suppressed in the increase of the odor intensity after the absorption of oxygen and having an excellent oxygen absorption performance over a wide range of humidity conditions from low humidity to high humidity, and provides an oxygen absorbent package using the oxygen absorbent composition. The oxygen absorbent composition of the present invention includes at least one compound having a tetralin ring represented by the following general formula (1) and a transition metal catalyst:
摘要:
A composition-of-matter for use in water treatment, composed of a water-insoluble matrix and one or more amidohydrolase, such as cyanuric acid amidohydrolase, incorporated in or on the matrix, is disclosed. Also disclosed are devices containing same and methods utilizing same for water treatment. The water treatment is effected by an enzymatically-catalyzed reduction of the concentration of an amide-containing compound, such as cyanuric acid, found in chlorinated water of swimming polls, spas and other similar structures.

摘要:
A container houses an absorbent for absorbing a gas such as oxygen, and can house an absorbent which reacts with a gas to expand as well as can house an absorbent which has a small diameter or whose diameter decreases without leakage, while securing air permeation between the inside and outside of the container. An absorbent-containing container has a lid body and a bottomed-cylindrical container main body having an opening in an upper surface which is covered by the lid body and which has a paper layer as an inner layer. The lid body is fitted in the opening with an outer peripheral portion being bent upward and held in contact with an inner layer of the container main body. An upper end portion of the container main body is bent from above the lid body toward the lid body to grip the outer peripheral portion of the lid body.
摘要:
The oxygen absorbent composition of the present invention at least contains a polyester oligomer containing a constitutional unit having a predetermined tetralin ring and a transition metal catalyst. It is preferable that the oxygen absorbent composition of the present invention further contains a thermoplastic resin.
