A clumpable animal litter comprises composite particles of filler materials, such as limestone and sand, and sodium bentonite. The filler materials have a lower bulk density as compared to a granular mixture of the same percentage of filler and sodium bentonite clay and contain up to eighty-five percent less clay.

A dryer cartridge for removal of water from a liquid is provided with a cartridge body having a receiving chamber and a cartridge body wall delimiting the receiving chamber at least in sections thereof, wherein the cartridge body wall allows the liquid to flow through. A drying agent is arranged in the receiving chamber. A connection head is provided that can fasten the dryer cartridge in an opening of a housing wall of a device for receiving the liquid. The connection head has a connection opening and the connection opening connects in fluid communication the receiving chamber to an environment of the cartridge body. A drying system is provided with a device for receiving the liquid and with the dryer cartridge that can be fastened to an opening of a housing wall of a device for receiving the liquid.

The present disclosure relates to hollow core granules, products incorporating the hollow core granules, and methods of making the hollow core granules. The hollow core granules can comprise at least one wall surrounding a cavity that is devoid of any solid or liquid so as to define a hollow core, the at least one wall comprising a plurality of individual particles of at least one wall forming material, the plurality of individual particles sufficiently bound together so that the at least one wall is structurally self-sustaining. The hollow core granules further can include a binder material present in the at least one wall. The hollow core granules can be useful as a standalone material and/or may be useful in preparing a variety of products wherein the hollow core granules may be mixed or otherwise combined with further components. The disclosure further provides methods of making such hollow core granules.

A promoted carbon and/or non-carbon base sorbent are described that are highly effective for the removal of mercury from flue gas streams. The promoted sorbent comprises a carbon and/or non-carbon base sorbent that has reacted with and contains forms of halogen and halides. Optional components may be added to increase and/or preserve reactivity and mercury capacity. These may be added directly with the base sorbent, or in-flight within a gas stream (air, flue gas, etc.), to enhance base sorbent performance and/or mercury capture. Mercury removal efficiencies obtained exceed conventional methods. The promoted sorbent can be regenerated and reused. Base sorbent treatment and preparation methods are also described. New methods for in-flight preparation, introduction, and control of the active base sorbent into the mercury contaminated gas stream are described.

A particulate composition said composition comprises a metal carbonate and/or a metal bicarbonate and a compound of aluminium, characterised in that the weight ratio of metal carbonate plus metal bicarbonate compounds to said compound of aluminium is at least 3:1. The composition is useful for removing halogenated compounds from a hydrocarbon-containing process stream.

The invention relates to a method to produce a particulate activated carbon material for capturing CO.sub.2 from air,

wherein the particulate activated carbon is impregnated with alkali carbonate salt such as K.sub.2CO.sub.3; and wherein the impregnated particulate activated carbon either has, determined using nitrogen adsorption methods, a pore volume of at least 0.10 cm.sup.3/g for pore sizes of at least 5 nm and a pore volume of at most 0.30 cm.sup.3/g for pore sizes of less than 2 nm or is based on a mixture of different alkali carbonate salts, or has a particular pore surface for pore sizes in the range of 2 nm-50 nm.

It is an object of the present invention to provide a filter which remove acidic gas in the atmosphere with high efficiency and has excellent water resistance. A filter comprising: an aluminium substrate; and an adsorption layer on a surface of the aluminium substrate, wherein the adsorption layer contains activated carbon, a manganese oxide, and an acrylic resin having a pH of 3.0 to 6.5.
