Vol 1 Chapter 8: Removal of CO2 from low pressure flue gas streams using carbon fibre composite molecular sieves and electric swing adsorption

Paul Hurst, BP plc, UK

Abstract: A novel separation technology based on electric potential field desorption of CO2 from a carbon fibre composite adsorbent was proposed by the Carbon Materials Technology Group at Oak Ridge National Laboratory. This paper, Removal of CO2 from low pressure flue gas streams using carbon fibre composite molecular sieves and electric swing adsorption, describes the experimental work and results from laboratory testing of the concept by the CCP Post-Combustion Technology Team. It was determined that the desorption step was controlled by surface heating of the composite adsorbent rather than a change in surface potential so originally believed. Electric power demands would make commercial application at the required scale uneconomic.
