The preparation and oxygen permeability of calcium-doped Ba–Sr–Ca–Co–Fe–O perovskite material

Selective production of ethylene via continuous oxidative dehydrogenation of ethane in (Dy2O3/MgO)-(Li-K)Cl composite membrane reactor

“…We could not find any report on oxygen permeation through (Dy 2 O 3 /MgO)-(Li-K)Cl composite membrane. But we can note that the oxygen permeation influx obtained in this study was larger than that (0.15 μmol s −1 cm −2 ) reported for Ba-Sr-Ca-Co-Fe-O perovskite membrane under similar conditions (T = 923 K)[39]. Activation energy exacted from Arrhenius plot yielded a value (6 kJ mol−1 )…”

Oxygen-permeable ceramic membrane with improved mediate-temperature stability based on partially A-site doped KxSr1-xCo0.8Fe0.2O3-δ

“…Oxygen permeation test of K x Sr 1−x Co 0.8 Fe 0.2 O 3−δ membranes was performed in our homemade apparatus, which was described elsewhere [26]. For oxygen permeation test, the membrane disks were firstly polished to certain thickness using 1000-mesh SiC papers.…”
