Abstract

Mesocellular siliceous foam (MCF) - branched polyethyleneimine (BPEI) composite powders were prepared via wet infiltration, then processed in accord with patented shaping technology, to produce robust MCF-BPEI composite pellets. Thermogravimetric analysis of CO₂ partial pressure swing adsorption (PPSA) processing of these sorbents was conducted to assess their potential for application to CO₂ post combustion capture (PCC) via adsorption processes, under anhydrous and highly humidified (15% H₂O) conditions. The pellet products were found to provide large CO₂ working capacities and high water tolerance under key process conditions, and, so, are considered highly prospective for CO₂ PCC.
