Previous: A Dual Function Material For The Adsorption And Conversion Of CO2 to Fuel

Anglo American Sponsorship, 09/2015 - 09/2019

Conventional CO₂ capture and sequestration (CCS) is a very energy-consuming process in amine solutions (CCS) is very energy intensive. We have developed an advanced technology which adsorbs CO₂ from flue gas and catalytically converts it to synthetic natural gas with our patented dual functional material (DFM). The DFM is composed of nano- dispersed CaO and Ru sites, respectively functioning as the CO₂ adsorbent and methanation catalyst. For industrial applications, the influences of effluent gas environment (temperature, flow rate, O₂, steam, composition, impurities, pressure drop and life) on the catalytic performance needs to be understood. The present project is focused on the scale-up study of CO₂ utilization in various industrial applications. Various catalyst synthesis methods for industrial mass production, and reaction process parameters for optimum catalytic performance a are under investigation. Enhanced materials are also being sought.
