Application of a membrane reactor system to thermal decomposition of CO2

Hydrogen‐assisted Carbon Dioxide Thermochemical Reduction on La0.9Ca0.1FeO3−δ Membranes: A Kinetics Study

“…Isothermal redox systems have also been developed to overcome these disadvantages . Moreover, CO 2 splitting in an isothermal oxygen‐permeable membrane reactor that operates at temperature as high as 1500 °C was proposed in the 1980s and recently achieved on a ceria membrane . Compared with thermochemical cycles, this membrane reactor has some advantages, for example, isothermal operation and process intensification into a single reactor unit.…”

Investigation of chemical stability and oxygen permeability of perovskite-type Ba0.5Sr0.5Co0.8Fe0.2O3−δ and BaCo0.7Fe0.2Nb0.1O3−δ ceramic membranes

“…These membranes have been widely studied for the applications in oxygen separation [1], solid oxide fuel cells [2] and in the field of chemical processing including partial oxidation of methane to syngas [3,4], pollutant (e.g. CO 2 ) reduction [5], selective oxidation of hydrocarbons [6] and so on.…”

Solid State Electrochemistry

“…The separation of CO 2 into CO and 1/2O 2 is also based on MIECs 70 . If operated at high temperatures (∼2000 °C) a significant fraction of CO 2 decomposes under equilibrium conditions and the oxygen generated can be pumped away after permeation through an MIEC ceramic membrane.…”
