Abstract
A novel crosslinked microporous polymer was synthesized via a modified acid-catalyzed Friedel-Crafts polycondensation reaction. By virtue of the rigid and polarizable monomers (aniline and pyrrole), the polymer, termed KFUPM-4, was proven permanently porous (Brunauer-Emmett-Teller surface area = 650 m2 g−1) with a high CO2 capacity (33 cm3 g−1 at 760 Torr and 298 K) and selectivity (CO2:CH4 selectivity = 15:1 at 298 K). As a result of these properties, KFUPM-4 was subjected to breakthrough measurements, whereby the material's ability to selectively capture CO2 under dynamic conditions from both dry and wet mixed gas streams was clearly demonstrated.
