The present disclosure relates, according to some embodiments, to an absorptive solid (e.g., an animal bedding) produced from a microcrop such as Lemna. An absorptive solid of the present disclosure may comprise (i) an odor-absorbing amount of chlorophyll, and (ii) a carbohydrate extracted from a microcrop, the carbohydrate itself comprising at least some of the odor-absorbing amount of chlorophyll. A process for generating an absorptive solid may comprise the actions of: (i) lysing a microcrop consisting of at least one photosynthetic aquatic species to generate a lysed microcrop; (ii) separating the lysed microcrop into a solid fraction and a juice fraction; (iii) separating the solid fraction to form a solid; and at least one of: (a) milling the solid to generate an absorptive powder, (b) shaping the solid to generate the absorptive pellet or an absorptive granule; and (c) extruding the solid to generate an absorptive extrudate.

A silica aggregate includes primary silica particles aggregated, the primary silica particles having an average particle size of 1 nm or more and less than 10 nm, the primary silica particles being crosslinked to each other by a bond containing a siloxane bond.

Polymeric adsorbents useful for solid phase extraction (SPE) comprising a copolymer formed by copolymerizing at least one hydrophobic monomer including divinylbenzene and at least one hydrophilic monomer including acrylonitrile. Also provided are SPE cartridges including a divinylbenzene-acrylonitrile hydrophilic-lipophilic balance adsorbent. Further provides are methods of using a divinylbenzene-acrylonitrile hydrophilic-lipophilic balance adsorbent in conventional and simplified SPE techniques.

An absorbent apparatus is provided for an air dryer purge air cleaner. The absorbent apparatus comprises a volume for containing absorbent material. The absorbent apparatus also comprises absorbent material that is both oleophilic and hydrophobic and is packed in the volume to provide a packed bed of absorbent material with a predetermined packing density. The packing of the material provides for a first and second flow path of an effluent stream through the absorbent material.

The present invention relates to a silica powder storage package that stores a silica powder, in which the silica powder storage package preferably includes a bottomed container that has an opening portion, and a lid member that closes the opening portion, and further relates to a test kit including the silica powder storage package of the present invention, and the test kit being for allowing the silica powder to adsorb at least one part of the components in a liquid sample by injecting the liquid sample into the bottomed container.

Process for conditioning a container including a granular material A enabling the adsorption of the nitrogen contained in a feed gas stream, including a step of injecting, into the container, a gas or a gas mixture G such that the adsorption capacity of the material A with respect to G is less than 10 Ncm.sup.3/g at 25 C. and 1 atm.

Cartridges useful in regenerating or purifying dialysis solutions are described as well as methods to regenerate or purify spent dialysis solutions. Dialysis methods using the sorbent cartridges of the present invention are further described.

The present disclosure relates, according to some embodiments, to methods and systems for deriving odor- and moisture-absorbing products from a microcrop (e.g., photosynthetic aquatic species). More specifically, the present disclosure relates, in some embodiments, to forming an absorptive product from Lemna, including an animal litter, an animal bedding, a diaper product, a spill clean-up product, and any combination thereof. A process for forming an absorbent product from a microcrop may comprise the actions of (a) lysing the microcrop to generate a lysed microcrop; (b) separating the lysed microcrop into a solid fraction and a juice fraction; (c) processing the solid fraction to generate an absorbent solid; and/or (d) forming, by a shaping unit, the absorbent solid into pellets or granules that may be incorporated into the absorptive product. An absorptive product may have odor-reducing properties that are due in part to chlorophyll (e.g., from a microcrop).

An absorbent apparatus is provided for an air dryer purge air cleaner. The absorbent apparatus comprises a volume for containing absorbent material. The absorbent apparatus also comprises absorbent material that is both oleophilic and hydrophobic and is packed in the volume to provide a packed bed of absorbent material with a predetermined packing density.

Particle loading assembly and method for loading particles into a vessel to form a densely packed particle bed comprising an inner layer of particles and an outer layer of particles. The inner layer of particles is arranged radially and concentric with the outer layer of particles. The inner layer of particles contains at least a first type of particle of different granulometry or range of composition or both granulometry and range of composition from a second type of particles contained in the outer layer.
