“…The stability of the OPM can also be improved by co-doping the OPM materials with less-reducible metals, e. (LBFZ-0.2) was used in a membrane reactor for the POM [140]. An oxygen permeation flux of 12 ml/min cm 2 was obtained in the LBFZ-0.2 disk membrane reactor applied in POM with the thickness of 0.5 mm, which can be operated steadily for more than 500 h at 900°C.…”

“…Markov et al [141] also found the long-term stability of a tubular membrane with lanthanum-strontium ferrite, which can be operated in POM steadied for more than 7000 h with the CO selectivity and CH 4 conversion above 90% and 98.8%, respectively. These results have been summarized in Table 2 [ [137][138][139][140][141][142][143]. In the POM, the main side reactions are the methane combustion with O 2 to H 2 O, CO 2 and produced H 2 and CO was totally oxidized to H 2 O and CO 2 .…”

The planar membrane reactor configuration was explored for partial oxidation of methane (POM) to syngas. A supported membrane composed of yttria-stabilized zirconia and La 0.8 Sr 0.2 Cr 0.5 Fe 0.5 O 3-d was sealed to a stainless holder, and a Ni/Al 2 O 3 catalyst bed was placed under the membrane plane with a small slit between them. This reactor configuration would facilitate the POM reaction via oxidation-reforming mechanism: the oxidation reaction occurring at the membrane surface and the reforming reaction taking place in the catalyst bed. At 8008C and a methane feed rate of 32 mL min 21, the reactor attained methane throughput conversion over 90%, CO and H 2 selectivity both over 95%, and an equivalent oxygen permeation rate 1.4 mL cm 22 min 21 . The membrane and catalyst remained intact after the POM testing. The planar membrane reactor configuration explored in this study may lead to the development of a compact reactor for syngas production.

“…These oxygen selective ceramic membranes can also be applied as membrane reactors for partial oxidation of low hydrocarbon to alkene or syngas [14][15][16][17][18][19][20][21][22][23]. Several studies demonstrate the feasibility of using MIEC membrane reactor to combine the air separation and reaction in a single unit for these high temperature methane oxidations [14][15][16][17][18][19][20][21][22][23]. Low material stability is the only factor that preventing these membranes in practical applications, especially in the presence of acidic gases such as CO 2 , NO x , H 2 S and reducing gases of CH 4 and H 2 [21][22][23][24].…”
