Abstract

Currently, the most effective and cost-friendly source of energy for modern society is burning fossil fuels at power plants. However, this method produces greenhouse gases, such as carbon dioxide (CO2), which instigate a hazardous climate-change when emitted into the atmosphere. The kind of gas that is produced from combustion is called flue gas and is composed of N2, O2, and CO2. To prevent emission, the CO2 must undergo either carbon capture and storage (CCS) or carbon capture and conversion (CCC) to be transformed into useful chemicals. However, the cost and energy penalty to implement current industrial technologies of CCS and CCC are so high that the overall plant efficiency and cost of electricity could be significantly impacted. This project focuses on developing a new class of cost effective and energy efficient mixed electron and carbonate-ion conductor (MECC) membranes. Each membrane is composed of a silver matrix and molten carbonate in order to separate the CO2 from the simulated flue gas and then dry reform with CH4 to produce syngas (H2 and CO). The silver matrix is stabilized for high temperatures (≥ 650°C) by coating a nanoscaled layer of ZrO2 using atomic layer deposition (ALD). This research focuses on investigating the dry methane reformation (DMR) performance and stability of the prepared MECC membrane reactor.
