Abstract
Supported amine sorbents, prepared by impregnation of silica and polymer supports with tetraethylenepentamine (TEPA) and polyethylenimine (PEI) are evaluated for CO2 capture from atmospheric air. The effect of CO 2 concentration and temperature is investigated. Regeneration was done at elevated temperatures up to 150°C and CO2 pressures up to 10 bar. Two potentially attractive fields of application were identified: (1) production of CO2 enriched air using low regeneration temperatures and (2) the production of pure CO2 at elevated pressure. The latter option can be considered for geoengineering (via CCS) or for synthetic fuels from renewable energy and atmospheric CO2.
