Abstract

Dense membranes of mixed-conducting perovskite-type oxides La_0.6Sr_0.4,CO_0.8Fe_0.2O₃ and La_0.8Ba_0.2Co_0.8Fe_0.2O₃ were used for methane coupling by application of pressure-driven O₂ permeation. High operating temperatures, typically above 800°C, were needed to obtain reasonable oxygen fluxes. Conversions were small (1–3%). Both compositions showed comparable C₂ selectivities at low methane partial pressures. At higher pressures the selectivity to C₂ hydrocarbons for La_0.6Sr_0.4CO_0.8Fe_0.2O₃ increased to 67%, whereas La_0.8Ba_0.2CO_0.8Fe_0.2O₃ showed small C₂ selectivities. Strong surface segregation of Sr and Ba was shown by SEM for both compositions.
