Preparation of Pd-TS-1 Composite Membrane for Hydrogen Separation

Abstract:

Article Preview

Palladium composite membranes have been prepared by improved electroless plating on macroporous α-Al2O3 tubes. TS-1 zeolite layer was introduced in the palladium composite membrane to modify macroporous α-Al2O3 tubes and prevent the diffusion between Pd and alumina. The detailed microstructure and morphology of the Pd-TS-1 composite membrane were examined by SEM and XRD. Moreover, gas permeation performance was tested at the temperature range of 623~773K. Results showed that the H2 permeance and H2/N2 ideal selectivity for Pd-TS-1 composite membrane could be up to 3.7×10-7 mol·m-2·s-1·Pa-1 and 310 at 773K, respectively.
