Title: One-pot and isothermal protocol for CO2 Capture and Utilization (CCU) by a New Dual Functional Materials (DFM)

Abstract

Recently, issues of efficiency and environmental impact have become causes of serious global concern in the industry. Due to the CO2 accumulation and the rising demand of energy, the development of sustainable energy technologies and reduction of carbon dioxide in the atmosphere via CO2 capture, storage, and utilization (CCSU) are the two important and effective strategies in dealing with current environmental issues viz. reduce greenhouse gas emissions and associated climate change. This project focuses on the synthesis DFMs as a promising catalytic solution for the development of sustainable energy technology and capture and conversion of CO2 to high-value products. The CO2 is captured from a flue gas and catalytically converted to synthetic natural gas (i.e., CH4) using H2 generated from renewable source on the DFM. The stored H2 used for methanation is assumed to be afforded by water electrolysis using excess alternative wind or solar energy. The primary commercial target of this project will be focused on power plant exhaust gases containing molecular oxygen and steam, as well as fermentation, landfill, and cement manufacturing effluents where O2 and steam are absent. Therefore, an aging test consisting of the cyclic test using CO2/N2 and a simulated O2-and-steam-containing flue gas for the adsorption will be conducted in 10 g scaled up the reactor with DFM pellets instead of DFM powders and cycle tested in a larger scale fixed bed reactor. DFM pellets are more consistent with industrial processes since fine powdered materials have high-pressure drop and create operational, technical and health problems for workers.
