    摘要： The present invention provides a gas separation system suitable for separating a gas mixture efficiently. A gas separation system 100 of the present invention includes: a first separation membrane 11 that separates a gas mixture 70 into a first permeated gas 80 and a first non-permeated gas 81; and a second separation membrane 21 that separates the first non-permeated gas 81 into a second permeated gas 90 and a second non-permeated gas 91. The gas mixture 70 contains a gas A and a gas B different from the gas A. The first separation membrane 11 allows the gas A to preferentially permeate therethrough. The second separation membrane 21 allows the gas B to preferentially permeate therethrough. A membrane area of the first separation membrane 11 is smaller than a membrane area of the second separation membrane 21. The gas separation system 100 recovers each of the second permeated gas 90 and the second non-permeated gas 91.

    摘要： [Problem] Provided is a semipermeable membrane that achieves chemical resistance (chlorine resistance, acid resistance, alkali resistance), membrane performance, and membrane strength by sulfonating a polyphenylene-based semipermeable membrane base material under specific conditions. [Solution] A polyphenylene-based semipermeable membrane that is composed of a material containing a polyphenylene-based resin, wherein the semipermeable membrane has a first surface of which at least a portion is sulfonated, and wherein, when concentration distribution of elemental sulfur derived from a sulfonic acid group is measured by elemental analysis in a cross section in a thickness direction of the semipermeable membrane, a ratio of a sulfonated layer obtained by the following expression is 50% or less: Ratio of Sulfonated Layer (%) = Sulfonated Layer Thickness / (Sulfonated Layer Thickness + Non-Sulfonated Layer Thickness) × 100.

    摘要： Mesoporous poly (aryl ether ketone) articles are formed from blends of poly (aryl ether ketones) with pore forming additives by melt processing, and can be in the form of a monofilament, disc, film, microcapillary or other complex shapes. The method of formation provides for preparation of poly (aryl ether ketone) articles with high degree of surface area and uniform nanometer pore size. The preferred poly (aryl ether ketone)s are poly (ether ketone) and poly (ether ether ketone). The mesoporous articles formed by the method of the present invention are useful for a broad range of applications, including molecular separations and organic solvent filtration.
