Project summary:

The project proposes a new, innovative solution for post-combustion CO2 capture (PCCC) which significantly reduces the high energy and efficiency costs associated with existing PCCC technologies. A suite of new hybrid solid sorbent materials based on activated carbon, carbon nanotubes and titania materials, and modified with amines or  with inorganic alkali, will be prepared and tested. The most promising sorbents will be identified from a preliminary physical and chemical property assessment and tested for selective CO2 adsorption from CO2/N2 mixtures under both static and dynamic regimes. To determine the effect of impurities on the adsorption efficiency, CO2 adsorption from a real combustion flue gas tested.
Measured adsorption isotherms will be fitted to various adsorption models and the best identified. The isosteric heats of adsorption will be estimated with the Clausius–Clapeyron equation. An essential aspect of the project is to develop a new, laboratory prototype moving bed absorption reactor to increase the solid sorbent CO2 absorption capacity.
Ultimately, the project aims to develop a new PCCC technology that can achieve a capture capacity of at least 5 mmol CO2/gsorbent (1 bar, 25°C), at least 50 CO2/N2 selectivity (at 1 bar, 25°C) and a sorbent deactivation level below 5% after 200 adsorption/desorption cycles. To complement the experimental approaches, mathematical reactor modelling will be developed to provide information about large scale reactor performance and power plant energy usage in the PCCC process. A combined literature and experimental environmental impact assessment of the solid sorbent materials will be performed. In addition to the technical aspects of the project, particular attention will be dedicated to raising social awareness of carbon capture and storage (CCS) issue. Activities will focus on highlighting the need for CCS technologies to reduce global CO2 emissions and also address public concerns regarding the safety of different CCS technologies.
