(519e) Improving the Efficiency of High Temperature Electrolysis of Carbon Dioxide in an SOC
AIChE Annual Meeting
Wednesday, November 13, 2019 - 2:00pm to 2:20pm
Here we focus on the development of a bespoke rig which allows for the simultaneous use of non-thermal plasma (NTPs), oscillating gas flow via a Desai-Zimmerman fluidic oscillator, and an SOC to create a highly efficient energy conversion device to facilitate the reduction of carbon dioxide to carbon monoxide. An analysis of the role of NTPs in improving the kinetics and efficiency of reactions, such as dissociation of carbon dioxide to form adsorbed oxygen ions in an SOC, thereby decreasing activation polarization is presented. Performance improvements using a rapidly oscillating gas flow provided by a Desai-Zimmerman fluidic oscillator to minimises concentration polarisation resistance by disrupting boundary layer formation and increasing the overall efficiency are also discussed. The intersection of these three technologies provide a path for a paradigm shift in the ability to convert waste carbon dioxde into high value feedstocks using renewable energy.
