Abstract: The present invention relates to an organic-inorganic hybrid nanoporous material, maintaining a nanoporous skeleton structure formed by coordination of an organic ligand containing an aromatic compound to a trivalent central metal ion, and further having an intramolecular acid anhydride functional group modified on the aromatic compound of the nanoporous skeleton structure, and thereby exhibits selectivity for olefins, and an adsorbent comprising the same. Specifically, the organic-inorganic hybrid nanoporous material of the present invention exhibits an excellent olefin-selective adsorption capacity through differences in adsorption equilibrium and adsorption rate, and thus can be usefully employed in the separation of C2-C4 hydrocarbons.

Abstract: The present invention provides an energy-saving air dryer comprising: a compressor for compressing the air in the atmosphere to form compressed air; a heat exchanger which is disposed on one side of the compressor and recovers compression heat from the compressed air; a pre-filter which is disposed on one side of the heat exchanger and removes pollutants from the compressed air; a pair of adsorption towers which communicate with the pre-filter and are filled with an adsorbent, wherein dry air is formed when compressed air flows into the adsorption towers according to the opening and closing of a valve and moisture is adsorbed, or moisture is desorbed from the adsorbent when dry air retaining the compression heat recovered in the heat exchanger is transferred to the adsorption towers; and an after filter which extends from the one side of the adsorption towers and removes pollutants from the dry air from which moisture has been removed.

Abstract: Disclosed herein is a nanoporous hybrids formed by covalent bonding between a crystalline organic-inorganic hybrid and a gigantic mesoporous metal oxide, containing organic groups on the surface thereof, having a size of 10 nm or more. Since the covalently-bonded hybrid nanoporous composite has a large surface area, a multiple microporous structure, a large pore volume and includes an organic-inorganic hybrid having backbone flexibility, the covalently-bonded hybrid nanoporous composite can be used as materials for storing liquids and gases, such as hydrogen, methane and the like, and can be used as adsorbents, separating materials, catalysts, and the like. Further, the covalently-bonded hybrid nanoporous hybrids can be used in the application fields of biomolecule supporting, drug delivery, harmful material removal, nanoparticle supporter, sensors, catalysis, adsorbents, fluorescent materials, solar cells, and the like.
