| Popis: | Here we report carbon-based composites polyethylenimine-mesocarbon (PEI-CMK-3) and polyvinylamine-mesocarbon (PVA-CMK-3) that can be used to capture and rapidly release CO(2). CO(2) uptake by the synthesized composites was determined using a gravimetric method at 30 °C and 1 atm; the 39% PEI-CMK-3 composite had ~12 wt % CO(2) uptake capacity and the 37% PVA-CMK-3 composite had ~13 wt % CO(2) uptake capacity. A desorption temperature of 75 °C was sufficient for regeneration. The CO(2) uptake was the same when using 10% CO(2) in a 90% CH(4), C(2)H(6), and C(3)H(8) mixture, underscoring this composite's efficacy for CO(2) sequestration from natural gas. |
