Adsorption and membrane processes are investigated for carbon capture applications. Breakthrough and isotherm experiments are carried out on carbon-based sorbents to investigate the kinetics and material capacities. Simulations using Grand Canonical Monte Carlo are carried out to assist in sorbent design (pore structure and chemistry). Similar models are used to investigate gas (CO2, methane, water) transport in nanoporous systems of coal and gas shale rocks. Nitrogen-selective membrane technology is also investigated for carbon capture.
