Oxidative coupling of methane (OCM) is a direct route for converting methane into ethylene and ethane (C2). When performed in conventional packed bed reactors (PBRs) this process suffers from significant thermodynamic and kinetic limitations in the selectivity towards the desired products over almost all explored catalysts. We will show that a membrane/catalyst system with distributed oxygen feed (i.e. an O2- conducting membrane reactor) can give significantly higher C2 selectivity and yield compared to a PBR. We will discuss our work on identifying the O2- conducting membranes and catalysts that are selective for OCM and that can be integrated in a membrane/catalyst system. We will discuss the OCM activity and selectivity on these membrane/catalysts systems as well as the long term stability of the system.
