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.
