摘要: A spin dope composition produces a polymeric fiber useful in non-cryogenic gas separation. The composition includes polysulfone as the polymeric component, two solvents, in which the polymer is soluble, and a non-solvent, in which the polymer is insoluble. The solvents preferably include N-methyl-pyrrolidone (NMP) and N,N-dimethyl acetamide (DMAC), and the non-solvent preferably includes triethylene glycol (TEG). Fibers made from the present composition have been found to exhibit superior properties of gas flux and selectivity, as compared with fibers made from spin dopes having only one solvent component.

摘要: Novel low-pressure nanofiltration membrane composites for rejecting organic compounds are prepared by interfacial polymerization on a microporous hollow fiber supporting membrane. The interfacial polymerization reaction is carried out using an essentially monomeric polyamine reactant having at least two amine functional groups per molecule, and an essentially monomeric amine-reactive polyfunctional aromatic or cycloaliphatic acyl halide having at least two acyl halide groups per molecule. The composite can be fabricated by stepwise polymerization reactions with different reactant recipes at each step.

摘要: Disclosed is a method for producing a hollow fiber carbon membrane using a hollow fiber carbon membrane-forming material by means of a dry method or dry-wet method comprising a spinning step, a drying step, an infusibilization step, and a carbonization step as basic steps; wherein in the infusibilization step, heat treatment is performed at least two times at different temperatures, with the second temperature being higher than the first temperature. It is preferable that the second heat treatment is performed directly after the first treatment is performed, without once cooling to room temperature. The obtained hollow fiber carbon membrane has improved permeability, without reducing its separation coefficient.
