Abstract

Purification of natural gas and separation of methanol-to-olefins (MTO) products are essential yet energy-intensive processes in petrochemical industry. Adsorption separation utilizing porous materials is regarded as an energy-efficient alternative to traditional distillation method for hydrocarbon separation. In this work, we presented a comprehensive investigation of an ultramicroporous MOF (PCP-TPDA), which features multiple supramolecular binding sites for the separate natural gas and MTO products. The single-component gas adsorption results indicate that PCP-TPDA can preferentially trap larger size alkane molecules than CH₄ and separate effectively C₃H₆ from C₂H₄. Furthermore, breakthrough experiments validated the actual feasibility of purifying natural gas and MTO products over PCP-TPDA. Additionally, computational simulations revealed the pivotal roles of narrow channels and multiple supramolecular binding sites for separation performance.

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
