Overview
Review demonstrates metal-organic framework utility in complex hydrocarbon separations, highlighting pathways to energy-efficient industrial purification.
Key Points
- Evaluate the capabilities and structural mechanisms of metal–organic frameworks for separating complex mixtures of saturated, unsaturated, and aromatic hydrocarbons.
- Reviewed literature on metal–organic framework adsorbents investigated for industrial hydrocarbon separations.
- Assessed framework properties including internal surface area, pore geometry tuning, and surface chemical functionalization across alkane, alkene, and aromatic systems.
- Metal–organic frameworks effectively distinguish between hydrocarbon molecules possessing nearly identical physical structures, boiling points, and chemical reactivities.
- Customizable pore dimensions and surface chemistries permit highly selective separations relevant to industrial-scale petrochemical streams.
