An MOF-Based Single-Molecule Propylene Nanotrap for Benchmark Propylene Capture from Ethylene

Chem & Bio Engineering, Год журнала: 2024, Номер 1(11), С. 952 - 959

Опубликована: Июль 29, 2024

Highly selective capture and separation of propylene (C3H6) from ethylene (C2H4) presents one the most crucial processes to obtain pure C2H4 in petrochemical industry. The performance current physisorbents is commonly limited by insufficient C3H6 binding affinity, resulting poor low-pressure uptakes or inadequate C3H6/C2H4 selectivities. Herein, we realize a unique single-molecule nanotrap an ultramicroporous MOF material (Co(pyz)[Pd(CN)4], ZJU-74a-Pd), exhibiting benchmark capacity at regions. This MOF-based features sandwichlike strong multipoint sites perfect size match with molecules, providing ultrastrong affinity maximal Q st value (55.8 kJ mol-1). affords exhibit highest low pressures (60.5 103.8 cm3 cm-3 0.01 0.1 bar) record-high selectivity (23.4). Theoretical calculations reveal that perfectly size-matched pore cavities combined multibinding enable this maximize mainly accounting for its record selectivity. Breakthrough experiments further confirm excellent actual 1/99 50/50 mixtures, affording remarkably high productivities 17.1 3.4 mol kg-1, respectively.

ConspectusThe separation and purification of hydrocarbons are crucially important processes in the petrochemical industry, as they essential for producing high-quality chemicals fuels. However, traditional thermal-driven practices, such cryogenic distillation, notoriously energy-intensive, accounting a notable portion energy consumption industrial operations. This has spurred exploration development low-energy sustainable alternative technologies, among which adsorption/desorption-based with porous materials gained significant attention. Metal–organic frameworks (MOFs) emerging ideal hydrocarbon due to their exceptional porosity structural tunability. Account delves into latest advancements microporous MOFs separation, categorizing them based on pore structures: single array, tandem orthogonal array. Single-array feature uniformly arranged channel-like pores along axial direction, facilitating incorporation binding sites surfaces. One functional group used these applications is open metal (OMSs), can engage strong metal-π interactions unsaturated acetylene. For example, JNU-1 demonstrates increased increasing pressure acetylene induce-fit effect, where framework contraction behavior triggered by its OMSs. JNU-4 offers two per center molecules, greatly improving adsorption capacity. On other hand, introducing low-polarity groups, seen JNU-6-CH3, effectively enhance performance favor alkanes while maintaining integrity under humid conditions. Another methyl group-modified MOF, JNU-5-CH3, exhibits an acetylene-triggered gate-opening effect multiple supramolecular Tandem-array provide enhanced selectivity capacity through interconnection spacious cavities narrow apertures. instance, JNU-2 pore-channel interconnected structure improved efficiency C2H6/C2H4 hexane isomers.
