In the past few years, remarkable progress has been made in the synthesis of light olefins (C2-C4) from methanol or syngas. The separation of light olefins by porous materials is, therefore, an intriguing research topic. In this work, single-component ethylene (C₂H₄) and propylene (C₃H₆) gas adsorption and binary C₃H₆/C₂H₄ (1:9) gas breakthrough experiments have been performed for three highly porous isostructural metal-organic frameworks (MOFs) denoted as Fe₂M-L (M = Mn²⁺, Co²⁺, or Ni²⁺), three representative MOFs, namely ZIF-8 (also known as Materials (Basel, Switzerland)Efficient Propylene/Ethylene Separation in Highly Porous Metal-Organic Frameworks.PMC98219452018YFC1903303KM202210005009Liu XMXie LHWu YfalseEfficient Propylene/Ethylene Separation in Highly Porous Metal-Organic Frameworks.Light olefins are important raw materials in the petrochemical industry for the production of many chemical products.
