Abstract
A novel tube-form asymmetrical carbon membrane based on phenol-formaldehyde resin (PFR) is proposed in this paper. The membrane is composed of Ni-P alloy on exterior surface of carbon support membrane by electroless plating method after adding ferrous powders (<20&m) as active particles inside the membrane procurer. The results show that the H2, N2 and CO2 permeation rate through the composite Ni-P carbon membrane decrease and gas separation factors increase with increase of Fe content, and H2, N2 and CO2 permeation rates reach 0.44, 0.10 and 0.08 m3.m-2.s-1.MPa-1, respectively; H2/N2 and H2/CO2 separation factors are 4.2 and 5.5, respectively. The morphology of the membrane is measured by Scanning Electron Microscope (SEM).
