Abstract

The potential of novel polyethyleneimine (PEI) based sorbent and process designs to safeguard the stability of the PEI type sorbent stability for CO2 post combustion capture (PCC) via vacuum swing adsorption (VSA) application was investigated. In-situ thermogravimetric analysis (TGA) combined with CO2 partial pressure swing adsorption (PPSA) processing, Fourier Transform Infrared (FTIR) spectroscopy and lab scale VSA processing of adsorber columns were employed for this purpose. The inventions were found to inhibit the dehydration of ammonium carbamates into ureas, and, thereby, better maintain the integrity of the sorbent and its CO2 working capacity under key process conditions.
