CC3 crystalline membranes for CO2/CH4 separation

Moises Carreon | mcareon@mines.edu

The main objective of this project is to develop crystalline membranes made of porous organic cages for CO2/CH4 separation.

CO2/CH4 is a key gas mixture for natural gas purification. Currently, there is no example in the literature of CC3 membranes for any industrially relevant gas mixture separation. If successful, this project would lead to seminal work in the development of continuous CC3 membranes for the effective separation of CO2/CH4. This CC3 membrane is appealing for this separation because potentially can molecular sieve CO2 from CH4 due to its uniform limiting pore size (3.6 A) lying between the kinetic diameters of CO2 (3.3 A) and CH4 (3.8 A)
