  • Patent number: 8852322
    Abstract: A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.

  • Patent number: 8657924
    Abstract: The present invention relates generally to a composite adsorbent comprising at least a zeolite-containing CO2 removal adsorbent and 10% or more of a metal oxide having a heat capacity of at least 20 cal/mol-° K (83.7 J/(mol·K). The composite is preferably used in a multi-layered adsorption system in a cyclic adsorption process. The adsorption system comprises two or more layers wherein the first layer is at least a water vapor removal adsorbent, such as activated alumina, and the second layer is the novel composite adsorbent. The adsorption system is preferably used in a PSA prepurification process prior to cryogenic air separation.

  • Publication number: 20140044756
    Abstract: A method of making a multilayer filter and the multilayer filter made by the method. The method includes generally two steps. The first step is to coat a layer of nanofibers on a single side or both sides of a substrate medium to obtain a composite filter medium, and the second step is to fold the composite filter medium in a serpentine fashion to form a multilayer filter. The second step may alternatively be accomplished by stacking up a number of sheets of the composite filter medium to form a multilayer filter having a structure of two layers of nanofibers being sandwiched between two layers of said substrate medium. The resulting multilayer filter produced by either method contains at least one structural unit which has two layers of nanofibers being sandwiched between two layers of the substrate medium.

  • Patent number: 8636834
    Abstract: The invention relates to a safe hydrogen-storing tank that is easy to manufacture and enables the quick kinetic absorption of hydrogen, which reduces the variations in volume and has a low cost in terms of material and energy. The invention has the aim of providing a tank for storing hydrogen, including a hydrogen inlet (21) and a hydrogen outlet (22) in fluid communication with at least one solid body (10-11) capable of the exothermal absorption and endothermal desorption of hydrogen, wherein said at least one solid body (10-11) is made of a compacted material containing light metal hydride and a heat-conducting matrix, and wherein said at least one solid body (10-11) is in heat-transfer relation with at least one heat recovery material (42) free from salt or molten-salt compounds and capable of absorbing the heat generated by the hydrogen absorption and of releasing said absorbed heat so as to provide heat for hydrogen desorption.
