Activated carbon, CO2 capture, Adsorption, High pressure


The development of solid adsorbent materials is one potential route to significantly reduce the energy penalty associated with pre-combustion power generation, and reducing the environmental impact of anthropogenic CO2. In this paper, a commercial activated carbon was modified with amine with the aim of improving its surface affinity for CO2 capture.  The physical properties of the adsorbents have been evaluated and related to the materials CO2 adsorption capacity, determined using Thermogravimetric analysis at ambient pressure and high pressure volumetric analyzer (HPVA) at high pressure. Total pore volumes positively influenced the trend of adsorption capacities of the carbons at ambient condition while a positive adsorption trend was recorded with respect to micropore volume and surface area at high pressure. In addition, approximately 2.7 and 6.5 mmol g-1 of CO2 uptake was achieved at ambient and high pressures respectively. This is the first time a pressure of up to 4.1 MPa is employed on an amine modified commercial activated carbon for CO2 capture purpose.
