Metal-organic frameworks with two different-sized aromatic ring-confined nanotraps for benchmark natural gas upgrade.

ABSTRACT: Recovery of light alkanes from natural gas is of great significance in petrochemical production. Herein, a promising strategy utilizing two types of size-complementary aromatic ring-confined nanotraps (called bi-nanotraps here) is proposed to efficiently trap ethane (C₂H₆) and propane (C₃H₈) selectively at their respective sites. Two isostructural metal-organic frameworks (MOFs, SNNU-185/186), each containing bi-nanotraps decorated with six aromatic rings, are selected to demonstrate the feasibility of this method. The smaller nanotrap acts as adsorption sites tailored for C₂H₆ while the larger one is optimized in size for C₃H₈. The separation is further facilitated by the large channels, which serve as
