Propylene and propane have similar physicochemical properties, and thus their separation is challenging. Now, as an alternative to energy-intensive cryogenic distillation methods, a molecular sieving adsorbent with high propylene adsorption capacity has been shown to sieve propylene from propylene/propane mixtures to yield high-purity propylene.
