An adsorbent bed, including at least one elementary composite structure that includes adsorbent particles in a polymer matrix, wherein the adsorbent bed has a bed packing, &#x3c1;, defined as a volume occupied by the at least one elementary composite structure Vdivided by a volume of the adsorbent bed Vwhere &#x3c1;is greater than 0.60.

Adsorber

Adsorption based gas separation method

A solid adsorbent fiber includes a solid support fiber that is enveloped by a solidified polymeric binder and also adsorbent particles.

Method for manufacturing a solid adsorbent fiber

A composite fiber comprising sorbent particles (at 50 wt %) in a polymeric matrix that comprises a polymer or blend of polymers including at least one thermoplastic polymer, the extrudates being produced by thermal-induced phase separation or diffusion-induced phase separation from a dope suspension of the thermoplastic polymer, an optional solvent and the sorbent particles. The polymer or blend of polymers is able to withstand exposure to temperatures at or above 220&#xb0; C. without experiencing significant detrimental effects upon the sorbent capacity of the sorbent particles. The fiber exhibits an elongation at break of at least 5%.

Sorbent-loaded fibers for high temperature adsorption processes

One or more polymeric hollow fiber membranes are pyrolyzed to form one or more hollow fiber CMS membranes by directing a flow of pyrolysis gas through a polymeric membrane cartridge (including a porous center tube around which one or more green, polymeric, hollow fiber membranes is arranged) or a bundle of polymeric membranes (including a plurality of green, polymeric hollow fiber membranes oriented so that their ends are disposed with ends of the bundle) in a direction perpendicular to a length direction of the cartridge or bundle in order to sweep away off-gases that are formed during pyrolysis.

Hollow fiber carbon molecular sieve membranes and method of manufacturing using radial-flow pyrolysis

One or more polymeric hollow fiber membranes are pyrolyzed to form one or more hollow fiber CMS membranes by directing a flow of pyrolysis gas through a bundle of polymeric membranes (including a plurality of green, polymeric hollow fiber membranes oriented so that their ends are disposed with ends of the bundle) in a direction perpendicular to a length direction of the bundle in order to sweep away off-gases that are formed during pyrolysis.

A plurality of extrudates comprises sorbent particles (at 50 wt %) in a polymeric matrix that comprises a polymer or blend of polymers including at least one thermoplastic polymer, the extrudates being produced by thermal-induced phase separation or diffusion-induced phase separation from a dope suspension of the thermoplastic polymer, an optional solvent and the sorbent particles. The polymer or blend of polymers is able to withstand exposure to temperatures at or above 220&#xb0; C. without experiencing significant detrimental effects upon the sorbent capacity of the sorbent particles.

Sorbent-loaded beads for high temperature adsorption processes

A bead comprised of a matrix of at least 50 wt % adsorbent particles and a thermoplastic polymer or a blend of thermoplastic polymers, the thermoplastic polymer or blend of thermoplastic polymers exhibiting a Vicat softening temperature of at least 240&#xb0; C.

Adsorbent-loaded beads for high temperature adsorption processes

Entrained metal hydride particle are removed from a flow of hydrogen from a Mg-based hydride storage unit using not only a particle filter but improvements for reducing or eliminating drastic changes in flow. In addition to or alternative to removal of entrained metal hydride particles, methane produced by reaction of hydrogen with steel in a metal hydride system preferably operated above 350&#xb0; C. is removed downstream of the Mg-based hydride storage unit using an adsorption cartridge, preferably containing activated carbon.

Method of purifying hydrogen from a metal hydride storage system

System for purifying hydrogen from a metal hydride storage system

A carbon molecular sieve (CMS) membrane is made by pyrolyzing a polymeric precursor membrane in a pyrolysis atmosphere containing a sulfur-containing compound.

Manufacturing carbon molecular sieve membranes using a pyrolysis atmosphere comprising sulfur-containing compounds

An enclosure is filled with a filling gas according to the disclosed method. An enclosure is provided having an interior, a width, a height, a thickness, and fluid filling and exit holes fluidly communicating with the interior. Filling of the enclosure is commenced by directing a flow of the filling gas at a filling flow rate into the fluid filling hole. An oxygen concentration of gas exiting the fluid exit hole is sensed. The filling of the enclosure is stopped when the sensed oxygen concentration reaches a threshold concentration, wherein the threshold oxygen concentration and/or the filling flow rate are selected by a Decision Support Tool based upon the width, height, and/or the thickness.
