The CO2 capture capacity of silica-supported Tetraethylenepentamine (TEPA/SiO2) is reduced under the presence of excessive HCl and H2O.  HCl reacted with primary and secondary amine of TEPA, producing -NH3+ ion.  H2O injection suggests that the presence of H2O causes the removal of TEPA from the SiO2 surface in molecular form.
