Efficient Conversion of Carbon Dioxide into Methane using 3rd Generation Ionic Liquids, Phase I

Metadata Updated: November 12, 2020

This work directly addresses a technology of interest listed in Section 9, sub-section H1.01 In-Situ Resource Utilization, specifically "Highly efficient reactors for carbon monoxide/carbon dioxide (CO/CO2) conversion into methane (CH4)."

The proposal will investigate combining recent work that demonstrates outstanding CO2 sorption by third generation ionic liquids (ILs) without an increase in viscosity (even in the presence of water) with adaptations of recently developed methodology for electrochemically reducing and polymerizing CO2 in an aqueous IL to polyethylene. The intention is to demonstrate that this methodology is an excellent candidate for creating a highly efficient reactor for carbon dioxide conversion to methane. Unlike conventional electrolytes, ILs generally have very low vapor pressures. This will make it possible for them to be used in the much lower pressure Martian atmosphere without the problem of evaporation.

Our goal is to build on the results achieved by other research groups by using our own knowledge and years of experience working with ILs, including electrochemistry, to efficiently reduce CO2. We will prepare the task-specific 3rd generation ILs and then measure their electrochemical properties; i.e., conductivity, electrochemical window, etc. These are currently unknown but are important in order to ascertain whether these ILs are suitable for this application. Anticipating this will be the case, we will then test various electrodes, including TiO2 and silver cathodes, to determine which gives the most selective reduction of CO2 to methane. The efficiency of the process (including power requirements) will be quantified and compared to the Sebatier and Fischer-Tropsch processes.
