Abstract

Gas separation membranes which possess improved characteristics as exemplified by selectivity and flux may be prepared by coating a porous organic polymer support with a solution or emulsion of a plasticizer and an organic polymer, said coating being effected at subatmospheric pressures in order to increase the penetration depth of the coating material.

Gas Separation Using Organic-Vapor-Resistent Membranes In Conjunctin With Organic-Vapor-Selective Membranes

Patent Baker, Richard W [Palo Alto, CA]; Pinnau, Ingo [Palo Alto, CA]; He, Zhenjie [Fremont, CA]; ...

A process for treating a gas mixture containing at least an organic compound gas or vapor and a second gas, such as natural gas, refinery off-gas or air. The process uses two sequential membrane separation steps, one using membrane selective for the organic compound over the second gas, the other selective for the second gas over the organic vapor. The second-gas-selective membranes use a selective layer made from a polymer having repeating units of a fluorinated polymer, and demonstrate good resistance to plasticization by the organic components in the gas mixture under treatment, and good recovery after exposure to liquidmore » « less

Preparation of aligned nanotube membranes for water and gas separation applications

Patent Lulevich, Valentin; Bakajin, Olgica; Klare, Jennifer E.; ...

Fabrication methods for selective membranes that include aligned nanotubes can advantageously include a mechanical polishing step. The nanotubes have their ends closed off during the step of infiltrating a polymer precursor around the nanotubes. This prevents polymer precursor from flowing into the nanotubes. The polishing step is performed after the polymer matrix is formed, and can open up the ends of the nanotubes.

Enzymatically active high-flux selectively gas-permeable membranes

Patent Jiang, Ying-Bing; Cecchi, Joseph L.; Rempe, Susan; ...

An ultra-thin, catalyzed liquid transport medium-based membrane structure fabricated with a porous supporting substrate may be used for separating an object species such as a carbon dioxide object species. Carbon dioxide flux through this membrane structures may be several orders of magnitude higher than traditional polymer membranes with a high selectivity to carbon dioxide. Other gases such as molecular oxygen, molecular hydrogen, and other species including non-gaseous species, for example ionic materials, may be separated using variations to the membrane discussed.

Enzymatically active high-flux selectively gas-permeable membranes for enhanced oil recovery and carbon capture

Patent Rempe, Susan Lynne; Jiang, Ying-Bing; Vanegas, Juan; ...

A membrane structure for moving a gaseous object species from a first region having an object species first concentration, through the membrane structure, to a second region having an object species second concentration different from the first concentration is described. The membrane includes a supporting substrate having a plurality of pores therethrough, each of the plurality of pores defined by a first end, a second end and a surface of the supporting substrate extending between the first end and the second end as well as a nanoporous layer within the plurality of pores, wherein the nanoporous layer comprises a hydrophilicmore » « less

Thermal casting process for the preparation of anisotropic membranes and the resultant membrane

Patent Caneba, Gerard T. M. [Albany, CA]; Soong, David S [Albany, CA]

A method for providing anisotropic polymer membranes from a binary polymer/solvent solution using a thermal inversion process. A homogeneous binary solution is cast onto a support and cooled in such a way as to provide a differential in cooling rate across the thickness of the resulting membrane sheet. Isotropic or anisotropic structures of selected porosities can be produced, depending on the initial concentration of polymer in the selected solvent and on the extent of the differential in cooling rate. This differential results in a corresponding gradation in pore size. The method may be modified to provide a working skin bymore » « less
