“…For instance, the mixed oxygen ion and electron conducting membrane (MIECM) reactor, in which oxygen was separated from air and simultaneously fed into the methane stream without compromising the conversion and selectivity, was a good design for the partial oxidation of methane to syngas (POM) [1][2][3][4]. The employing of the MIECM reactor not only could directly use air as an oxidant, such that the product was free from the N 2 impurity component and the formation of environmental pollutants (e.g.…”

“…This drawback greatly hindered practical utilization of this material as oxygen separation membranes. In order to improve the electronic conductivity, and also to increase the oxygen permeation flux, multivalent metal oxides such as TiO 2 and Tb 2 O 3.5 were mixed into the lattices of YSZ and CSZ [16,17]. Unfortunately, the total conductivity was still not high enough for use in oxygen extraction due to the limitation of the solid solubility range of the multivalent oxides.…”

“…Ming and Ritchie [55,56] An alternative method to overcome the difficulties for the practical application of the perovskite membrane materials, such as chemical instability and low mechanical integrity, is to develop perovskite-related intergrowth oxides. Balachandran et al [57][58][59] firstly reported a MIEC material based on cobalt-doped Sr 4 Fe 6 O 13, i.e. SrFeCo 0.5 O x , which exhibits unusually high oxygen ionic conductivity (r 0~7 S cm )1 at 800°C in air) and oxygen permeability (2.5 ml/cm 2 min for a 2.9 mm thick membrane at 900°C) [27].…”

In this paper, oxygen permeable membrane used in membrane reactor for selective oxidation of alkanes will be discussed in detail. The recent developments for the membrane materials will be presented, and the strategy for the selection of the membrane materials will be outlined. The main applications of oxygen permeable membrane in selective oxidation of light alkanes will be summarized, which includes partial oxidation of methane (POM) to syngas and partial oxidation of heptane (POH) to produce H 2 , oxidative coupling of methane (OCM) to C 2 , oxidative dehydrogenation of ethane (ODE) to ethylene and oxidative dehydrogenation of propane (ODP) to propylene. Achievements for the membrane material developments and selective oxidation of light alkanes in membrane reactor in our group are highlighted.

“…Perovskite-type oxides LaACoFeO 3ࢬd Aࢼ Sr, Ba, Ca with a high ionic conductivity and prevailing electronic conductivity represent one of the most promising groups of mixed conductors. [10][11][12][13][14][15] Upon applying an oxygen partial pressure across a membrane made of a mixed conducting oxide, an oxygen permeation flux occurs under 900c C. The oxygen permeation process consists of oxygen exchanges between the gassolid interface, and the counter diffusion of oxygen ions and electronic species in the bulk of the membrane. 16 For enhancement of the oxygen permeation flux, a thin and dense membrane prepared on a porous and heat-resistant substrate was required.…”

The electrophoretic deposition EPD process is one of several ceramic powder assembling technologies using a simultaneous colloidal process and electrochemical driving force. For the further development of the EPD technique, the possibility and the usefulness of preparing a thin and dense ceramic coating on non-electronically conductive porous tubular ceramics using the EPD technique was investigated. La 0.8 Sr 0.2 Co 0.8 Sr 0.2 O 3ࢬd LSCF was used as the deposition material and a porous alumina tube was used as the deposition substrate. Methanol MeOH was suitable as a dispersing medium for the LSCF powder. LSCF particles were positively charged in MeOH. For the fabrication of a uniform EPD layer, the cathode was placed in a porous alumina tube. The insides of the porous alumina tubes were filled with MeOH and the cathode did not make contact with the EPD bath. A 30 mm 200 gm 2 thick uniform LSCF powder coating was obtained by EPD at 100 V for 10 min. After sintering at 1500c C for 5 h, a 20 mm dense membrane was obtained.
