Overview

Experimental study demonstrates single-cycle ethylene purification with 99.9% purity using a tailored metal-organic framework, highlighting a scalable route for low-energy hydrocarbon separation.

Key Points

To achieve efficient, one-step purification of ethylene by selectively capturing low concentrations of acetylene and ethane from ternary hydrocarbon mixtures using an engineered metal-organic framework.
Synthesized a layer-pillared microporous metal-organic framework, Ni(pca)(dabco), featuring 3D alkyl pillars and 5.4 Å pores that control oxygen atom accessibility.
Evaluated dynamic breakthrough separation performance at 298 K using a ternary C2H2/C2H6/C2H4 mixture in a 1/9/90 ratio.
Investigated guest-host binding mechanisms through computational simulations and in situ characterizations.
Ni(pca)(dabco) exhibited adsorption capacities of 2.76 mmol g⁻¹ for C2H2 and 2.58 mmol g⁻¹ for C2H6 at 0.1 bar and 298 K.
Dynamic breakthrough testing achieved a C2H4 productivity of 1.53 mmol g⁻¹ with 99.9% purity in a single separation cycle.
