The present invention describes the process of preparing ceramics for the absorption of ACIDIC gases, which worsen the greenhouse effect, that are released in combustion systems, or that are present in closed environments. In relation to carbon dioxide, principal target of the present invention, the process of absorption, transport, processing and transformation of the gas into other products is described. The process uses ceramic materials prepared through the solid mixture of one or more metallic oxides, with one or more binding agents and an expanding agent. The product generated can be processed and the absorbent system regenerated. The carbon dioxide obtained in the processing can be used as analytic or commercial carbonic gas, various carbamates and ammonium carbonate.

The application provides an oxide layer material capable of adsorbing and degrading methane gas, which is obtained by a method comprising the steps of: 1) subjecting a cracked household refuse to aerobic biological pretreatment; 2) subjecting the material which has been subjected to the aerobic biological pretreatment to biological stabilizing treatment; and 3) adding copper chloride, potassium sulfate, magnesium oxide, and a composite bacterial agent for oxidizing methane gas to the material which has been subjected to the biological stabilizing treatment to obtain the oxide layer material capable of adsorbing and degrading methane gas. This disclosure further discloses a method for preparing the oxide layer material capable of adsorbing and degrading methane gas described above.

Calcium silicate hydrate nanoparticles are combined with ammonia control materials (e.g. alum, aluminum chloride, ferric chloride, ferric sulfate, and/or sodium bisulfate) to create a phosphorus-binding composition. In the preferred embodiment, the composition is applied to poultry litter, poultry bedding or other non-aqueous substrates that are at least partially comprised of animal manure. The composition binds with phosphorus to at least reduce the amount of phosphorus in runoff water or in leachate from fields fertilized with treated manure. The combining of the calcium silicate hydrate nanoparticles with the ammonia control products has a surprising and unexpected result. The calcium silicate hydrate-ammonia control material mix reduces soluble phosphorus more than either component of the mix alone.

A method including adding to or positioning in a vehicle air conditioning system a solid form adsorbent. The solid form adsorbent includes a plurality of discrete adsorbent particles spatially bound in place by point bonding with a binder. At least about 25% of the external surface area of a majority of the particles is not sealed off by the binder and is available for adsorption.

Filter media comprising adsorptive particles are generally described. In some embodiments, the adsorptive particles are present in a relatively large amount, in a layer discrete from one or more other layers and/or fiber webs also present in the filter media, and/or in a layer that comprises a relatively low amount of fibers. In some embodiments, the filter media further comprises a non-woven fiber web comprising fibers with relatively small diameters.

An agglomerate is provided that can include an aluminosilicate (ash) base material and one or more of a binding agent or leach reduction agent. Each of the agglomerate and binding agent can include no more than about 25 wt. % cement.

A moisture absorbent for a vehicle lamp includes a first inorganic material, a second inorganic material, alkali metal phosphate, and a polymer wax are included. A composite moisture absorbent structure includes a first moisture absorbent pack including a powder type moisture absorbent and a second moisture absorbent pack including a capsule type moisture absorbent are embedded.

An activated carbon sorbent composition comprising activated carbon and a passivation agent, wherein the activated carbon sorbent composition exhibits reduced self-heating or auto-ignition properties as compared to the activated carbon. The activated carbon sorbent composition may be utilized to sequester contaminants such as mercury from a flue gas stream. The passivation agent includes a sulfur species, and may be a sulfur oxide compound, a sulfide compound, or an organic sulfur compound. Methods for the manufacture of the activated carbon sorbent composition and for the sequestration of contaminants in a flue gas stream using the composition are also disclosed.

Provided are a water-absorbing agent composition of high quality (and stable quality) that can be produced without a decrease in productivity and is not colored even in a production process (or under production conditions) under high temperature conditions (under the condition of heating at 100° C. or higher), even when a polysaccharide is used as a sustainable raw material for at least part of the water-absorbing agent composition, and a method for producing the water-absorbing agent composition. The water-absorbing agent composition includes: a polyacrylic acid (salt)-based water-absorbing resin; a polysaccharide, and a reducing agent. The water-absorbing agent composition is surface-crosslinked, contains the polysaccharide in an amount of 10 mass% or more and contains the reducing agent in an amount of 10 ppm to 10000 ppm, and has a degree of coloration (YI value) of 60 or less.
