One Component Membrane Reactor for Partial Oxidation of Methane Using Asymmetric Membranes

Oxygen permeable asymmetric membranes of Ca0.8Sr0.2Ti0.7Fe0.3O3−δ were applied to a one-component membrane reactor (OCMR) for the partial oxidation of methane. CH4 conversion and oxygen flux of OCMR with a 43-μm dense layer at 1173 K reached 71% and 1.7 mL min−1 cm−2, respectively. These values are...

Zusammenfassung:Oxygen permeable asymmetric membranes of Ca0.8Sr0.2Ti0.7Fe0.3O3−δ were applied to a one-component membrane reactor (OCMR) for the partial oxidation of methane. CH4 conversion and oxygen flux of OCMR with a 43-μm dense layer at 1173 K reached 71% and 1.7 mL min−1 cm−2, respectively. These values are 2.5 times greater than that of a 500-μm self-supported membrane.
