The present invention provides a porous body for the absorption of a liquid component contained in an ink image on an ink receiving medium, the porous body including a fiber having a pore structure in the inside, wherein the pore structure satisfies the following requirements (a) and (b), and an inter-fiber void ratio which indicates the volume ratio of a void formed between the each fibers is 40% or more to 80% or less: (a) average pore size/average fiber diameter is 0.2 or less; and (b) an intra-fiber void ratio is 5% or more to 40% or less.

The present invention relates to a porous formed article comprising an organic polymer resin and an inorganic ion adsorbent and having the most frequent pore size of 0.08 to 0.70 m measured with a mercury porosimeter.

The present invention also relates to a method for producing a porous formed article and a production apparatus for a porous formed article.

The present invention provides a process for preparing a functionalised polymeric chromatography medium, which process comprises (I) providing two or more non-woven sheets stacked one on top of the other, each said sheet comprising one or more polymer nanofibres, (II) simultaneously heating and pressing the stack of sheets to fuse points of contact between the nanofibres of adjacent sheets, and (III) contacting the pressed and heated product with a reagent which functionalises the product of step (II) as a chromatography medium.

An ammonia-containing liquid or an ammonia-containing gas is made to contact a porous coordination polymer in which a metal ion and an organic ligand coordinately bonded, ammonia is adsorbed to the porous coordination polymer, and the ammonia is desorbed from the ammonia-adsorbed porous coordination polymer to recover the ammonia. The porous coordination polymer that contacts the ammonia-containing liquid preferably has a water-soluble solvent adhered thereto. The ammonia-containing gas is preferably adjusted such that water is contained at an amount of 106 parts by mass or more when the ammonia content is 100 parts by mass.

Disclosed in certain embodiments are sorbents for capturing heavy hydrocarbons via thermal swing adsorption processes.

An anion exchange chromatography medium (1) for use in purification of enveloped virus particles or exosomes from a feed, the anion exchange chromatography medium comprising a support material being functionalized with a ligand comprising a diamine functionality generating at least one weak anion exchange group to an ionic capacity of 10-500 ?mol/mL.

The present disclosure provides a macroporous noble metal catalyst and processes employing such catalysts for the regeneration of deactivated ionic liquid catalyst containing conjunct polymer.

A cylindrical column-shaped honeycomb adsorbent has a plurality of cell passages extending along an axial direction of the honeycomb adsorbent. The plurality of cell passages are configured so that a pitch of adjacent cell passages is within a range of 1.5 mm1.8 mm, and so that a thickness of a wall between the cell passages is within a range of 0.45 mm0.60 mm. With this configuration, the honeycomb adsorbent exhibits BWC (Butane Working Capacity) of 6.5 g/dL or greater. By mixing fibrous meltable core melting away during baking, the honeycomb adsorbent has macropores configured to have a volume of 0.15 mL/g0.35 mL/g with respect to an overall weight of the honeycomb adsorbent and metal oxide particles having a proportion of weight of 150250% with respect to the activated carbon.

The present disclosure relates to a method of separating a compound of interest, particularly unsaturated compound(s) of interest, from a mixture. The compound is separated using a column having a chromatographic stationary phase material for various different modes of chromatography containing a first substituent and a second substituent. The first substituent minimizes compound retention variation over time under chromatographic conditions. The second substituent chromatographically and selectively retains the compound by incorporating one or more aromatic, polyaromatic, heterocyclic aromatic, or polyheterocyclic aromatic hydrocarbon groups, each group being optionally substituted with an aliphatic group.

A polysaccharide based aerogel comprising a network of polysaccharide fibers with pores therebetween, wherein the sizes of the pores are in the micrometer range.
