A water purification chamber is provided. In one embodiment, a system comprises a purification chamber comprising a selective adsorbent activated carbon fiber fabric including one or more selective functional groups that bind arsenic.

A method provides a buoyant sheet of compacted water Hyacinth particles having a size of between 1/32 inches and 1/16 inches, and a moisture content 10 percent, and a plurality of dry Hyacinth particles having a size of between 0.001 and 1 inch, and a moisture content 10 percent.

Sorbent material sheets products that include sorbent material sheets and at least one porous cover layer are attached to an inner wall surface that is defined by an air intake. The sorbent material sheets collect vapors such as hydrocarbon vapors from engine components such as the combustion chamber, injectors, carburetor, fuel ports, crankcase, or other engine components, thereby reducing evaporative emissions. In certain configurations, the sorbent material sheet product includes an edge seal that improves the handling of the sorbent material sheets during the manufacturing process.

Sorbent material sheets provide for enhanced performance in vapor adsorbing applications over conventional canisters and other emissions control equipment. The sorbent material sheets can be formed as part of a small, lightweight canister, or can be integrated into a fuel tank. The sorbent material sheets can also be used as part of an onboard refueling vapor recovery system to control volatile organic compound emissions from fuel tanks of gasoline vehicles, such as automobiles.

Carbon dioxide sorbent article assemblies and methods of manufacturing the same include: separable sheets of sorbent article disposed adjacent to each other to define a gap between adjacent separable sheets, the gap being maintained uniformly between opposing surfaces of adjacent separable sheets to define a passage extending between adjacent separable sheets from an inlet of the separable sheets to an outlet of the separable sheets; and a support framework supporting the separable sheets to maintain the gap, the support framework having a gap-maintaining component extending from the support framework along at least one separable sheet to maintain an initial position of the separable sheet.

Provided are a hygroscopic material which includes a resin layer, a hygroscopic layer, and a damp-proof layer in this order, in which the hygroscopic layer has a pattern structure having a first region that has a thickness A and a second region that is present at a peripheral edge of the first region and has a thickness smaller than the thickness A, and the damp-proof layer is provided on the first region and the second region; a method of producing the same; a packaging material; and a packaging item.

Polymeric amine solid sorbents with enhanced stability to moisture and/or oxygen for sorptive gas separation processes are disclosed. The polymeric amine solid sorbents can be supported on a porous support or integrated into solid porous polymer networks. Sorptive gas separators can employ contactors with such polymeric amine solid sorbents for separation of a component from a multi-component gas stream.

An oil skimming device for the removal of oil located at the surface of a body of water includes a float, at least one skimming surface, a sorbent material, at least one scraper, and a motor. The float is arranged such that the device rests on the surface of the body of water from which the oil is to be removed. The at least one skimming surface is rotatable about an axis such that when the device is floating in the water a portion of the ridged skimming surface is above and a portion of the skimming surface is below the water surface. The sorbent material is removably attached to and substantially covers the skimming surface. The sorbent material is configured to rotate with the skimming surface and to sorb oil as the skimming surface is rotated.

Construction for absorbing a fluid, for example, a liquid or gaseous, organic chemical, has an extended web, fabric, yarn or foam member and associated with the extended web, fabric, yarn or foam member is a water-insoluble polymer. The water-insoluble polymer can absorb the fluid organic chemical, and the construction provides for contact of the water-insoluble polymer with the fluid organic chemical when deployed in an environment where the fluid organic chemical may be present for absorption. The construction may be employed in aquatic, aqueous, or dry environments, as a blotter, a wipe or sponge, a filter, in a cartridge, and so forth.

A monolith for catalytic or sorbent purposes. The monolith includes a substrate sheet having attached thereto a plurality of catalytic or sorbent beads. Each bead has a diameter of at least fifty microns. The substrate sheet at least partially defines one or more channels through the monolith. Fluid flowing through the channels will contact the beads for catalytic or sorbent purposes.
