Abstract:

Plasma conversion technology is an emerging technique under development to activate, convert or valorize gas molecules such as CO2, N2, CH4, NH3 and others. A large-scale application beyond the lab-scale demonstrator unit requires assessment of the efficiency of this new technology. The straightforward approach for assessment of the efficiency is benchmarking with the other well-established technologies of similar technology readiness level (TRL). In this paper we present a benchmarking of the atmospheric pressure microwave-induced CO2 plasma splitting with electrochemical CO2 conversion, via both low-temperature and high-temperature electrolysis. An additional step of oxygen removal in case of the plasma reactor is implemented due to the difference in the output stream of the plasma (gas mixture containing CO2, CO, and O2) and the electrochemical reactor (typical gas mixture on cathode containing CO2 and CO). For the benchmarking, a comprehensive set of comparison parameters that are applicable for both the plasma and the electrochemical route is identified and grouped in three comparison categories: performance, interfaces, and economics. ... mehr
