Development of Superflux Carbon Nanotube Membranes for Gas Separation (2008–2012)
Carbon nanotube membranes have recently been theoretically predicted and experimentally shown to transport single component gases orders of magnitude faster than current conventional membranes. Theory also suggests that they can be made to have good selectivity, that is, to pass some gases through while preventing others. This project seeks to demonstrate experimentally superfluxes and high selectivity in CNT membranes. Guided by theory, the CNT membranes will be modified using metal doping to enhance selectivity for different gas separations including (as case studies) carbon dioxide from flue gas and from natural gas.
