In situ Synthesis of Polymer-Modified Mesoporous Carbon CMK-3 Composites for CO2 Sequestration

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 CO2. CO2 uptake by the synthesized composites was determined using a gravimetric method at 30 °C and 1 atm; the 39% PEI-CMK-3 compo...

description	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 CO2. CO2 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 % CO2 uptake capacity and the 37% PVA-CMK-3 composite had ∼13 wt % CO2 uptake capacity. A desorption temperature of 75 °C was sufficient for regeneration. The CO2 uptake was the same when using 10% CO2 in a 90% CH4, C2H6, and C3H8 mixture, underscoring this composite’s efficacy for CO2 sequestration from natural gas.
