CO2 capture using physical adsorbents such as activated carbon, zeolites, and metal-organic frameworks (MOFs) have attracted a lot of attention because of the technical capability of adsorption technology using such separation agents to retrofit the energy demanding liquid amine scrubbing process. Nevertheless, this will be conceivable only if the separation agents (adsorbents) in question fulfil many unambiguous attributes in terms of porosity, CO2 affinity, kinetics, energetics, stability, throughout the right capture mechanism, in addition to the adsorbents cost.
In this paper we report recent study about the evaluation of physical adsorbents for CO2 capture from simulated flue gas.
Extensive CO2/N2:10/90 mixed gas adsorption at 298 and 328 K, in the presence of water vapor and other impurities, were carried out using both temperature and pressure swing regeneration modes. For comparison purpose, absorption in liquid amines and adsorption on 13X zeolites are considered as the reference technologies for post-combustion CO2 capture.
