Electro-Oxidative Dehydrogenation of Ethane to Ethylene Using Lanthanum-Strontium-Iron Oxide Perovskite Electrocatalysts
Developing alternative, industrially viable ethylene production routes has received important research attention. One chemical pathway of interest is the oxidative dehydrogenation (ODH) of ethane, although issues such as product selectivity, combustion hazards, and oxidizer supply have hindered the practical scale-up of this technology. The presented work describes the use of a solid oxide fuel cell (SOFC) platform employing lanthanum-strontium-iron oxide perovskite (La 1-x Sr x FeO 3-δ , or LSFx) electrocatalysts to perform electrochemical-ODH (e-ODH), a process design that has the potential to address the challenges of ODH implementation. The effects of La and Sr stoichiometry, operating temperature, and current density are reported. The highest performance was observed using a La:Sr ratio of 0.50 (LSF0.50) at 750 °C and a current density of 0.50 A·cm –2 , achieving an ethane conversion of 18.7 ± 0.3%, ethylene selectivity of 91.4 ± 1.9%, and ethylene yield of 17.1 ± 0.1%. These results demonstrate several potential advantages for utilizing a SOFC platform to perform e-ODH of ethane to ethylene.

Novel Modular Electrocatalytic Processing for Simultaneous Conversion of Carbon Dioxide and Wet Shale Gas into Valuable Products
This report examines solid oxide electrolyzer cell (SOEC) technology as an alternative process for the manufacture of carbon monoxide (CO) and the separation of ethane (C 2 H 6 ) from wet natural gas (WNG). SOEC cathodes for the electrochemical reduction of carbon dioxide (CO 2 ) to CO and SOEC anodes for the selective electrochemical oxidation of C 2 H 6 to ethylene (C 2 H 4 ) are described and presented. Lifecycle and techno-economic analyses (LCA and TEA) utilizing SOEC technology for the production of CO are also reported.
