“…pure Ar. By oxygen temperature-programmed desorption technique (O 2 -TPD) Shao et al [22] found that the substitution of strontium ions in SCF by larger barium ions could effectively suppress the oxidation of Co 3+ and Fe 3+ to Co 4+ and Fe 4+ in the lattice and stabilize the perovskite structure under low oxygen partial pressures, e.g. pure Ar.…”

“…3 shows the XRD pattern of the hollow fibers after being sintered at 1100 1C. The XRD spectra exhibit patterns that shows seven strong diffraction peaks with respective 2y angles and lattice planes of 22.28 {1 0 0}, 31.72 {1 1 0}, 39.24 {1 1 1}, 45.52 {2 0 0}, 56.6 {2 1 1}, 66.36 {2 2 0}, and 75.72 {3 1 0}, which are related to the cubic perovskite phase of BSCF [9]. The calculated lattice parameter for BSCF is 0.3967 nm.…”

BSCF hollow fiber membranes possessing an asymmetric layered structure were prepared using a modified phase inversion process followed by subsequent sintering at temperatures from 1100 to 1175 1C. The fibers were characterized by SEM, and tested for air separation at ambient pressure and temperatures between 650 and 950 1C. Although the prepared hollow fibers resulted in self-supported asymmetric substrate with a very thin densified perovskite layer for mixed conduction, O 2 permeation was controlled by surface O 2 exchange kinetics rather than bulk diffusion. In order to improve O 2 flux, surface modification was carried out by the attachment of Pt particles on the surface of the hollow fiber. The maximum O 2 flux measured for pure perovskite hollow fiber was 0.0268 mol m À2 s À1 at 950 1C whilst O 2 fluxes increased up to 25% after the surface modification using Pt micro-particles. r

“…This work is to study the hydrogen production in a membrane reactor by combining air separation by this dense membrane with the partial oxidation of heptane, which is a typical component of gasoline. pared as described in the literature [9], and the catalyst LiLaNiO/␥-Al 2 O 3 was prepared via the impregnation method according to the report [10], and its performance is shown from the references [11][12][13][14]. Heptane was fed by a pump at a constant rate and the steam was brought by He, which was also used to adjust the partial pressure of the reactants.…”
