Propylene/propane separation by vacuum swing adsorption using Cu-BTC spheres

► Cu-BTC spheres (KRICT) are evaluated for propane/propylene separation. ► Cu-BTC spheres (KRICT) present the highest reported propylene adsorption capacity. ► Cu-BTC spheres (KRICT) tablets present a propane/propylene separation factor of 2. ► The results presented can be used to design a separation process.
