Permselectivity of a nickel/ceramic composite membrane at elevated temperatures: A new prospect in hydrogen separation?

Effect of nickel deposition on hydrogen permeation behavior of mesoporous γ-alumina composite membranes

“…The temperature dependence of hydrogen permeance for the Ni/alumina membrane was changed at high temperature range, suggesting the hydrogen penetration was facilitated by nickel at high temperature. This phenomenon was also observed for Ni-P/ceramic membrane [24]. Its H 2 /N 2 selectivity was not so high at high temperature.…”

Composite ceramic membranes from natural aluminosilicates for microfiltration applications

“…Most of the supports are generally manufactured from compounds such as alumina (Al 2 O 3 ) [18][19][20][21][22][23][24][25][26][27][28], cordierite (2MgO Á 2Al 2 O 3 Á 5SiO 2 ) [29][30][31]) and mullite (3Al 2 O 3 Á 2SiO 2 ) [32][33]. These materials have relatively elevated prices which significantly contribute to the cost of membrane modules for industrial applications.…”

Transport studies of nickel arsenate membrane

“…The characterization of membrane morphology has been studied by a number of investigators using scanning electron microscopy [18,19]. The composite pore structure, micro/macro porosity, homogeneity, thickness, cracks and surface texture/morphology have been studied [20,21].…”
