Selective sorption of water vapor from gas mixtures containing H2S, SO2, NO2, NO, and CO on KU-2 sulfonic styrene cation exchanger in different ion forms

Sorption of water vapor and some acid gases (H2S, SO2, NO2, NO, and CO) on Ku-23-15/100 macroporous sulfonic cation exchanger in different ion forms and on commercial KSM silica gel and NaX artificial zeolite was studied under equilibrium and dynamic conditions. The equilibrium isotherms of water vapor sorption were measured for all the adsorbents examined. The mechanism of water sorption on the sulfonic cation exchanger was discussed.
