Abstract
Experimental results are presented of the adsorption equilibria of water vapour over zeolite molecular sieves 13X (Molsiv and Grace) which may be used in the separation of CO2 from flue gas streams. It is found that water vapour is the strongest adsorbing species among the main components of the flue gas. It is also concluded that the H2O isotherms are strongly non-linear, so that even very small amounts of water vapour in a separated flue gas stream may significantly reduce CO2 sorption capacity of the two adsorbents studied.
