ZEOLITIC IMIDAZOLATE FRAMEWORKS FOR KINETIC SEPARATION OF PROPANE AND PROPENE

The separation of propane and propene by cryogenic distillation is one of the most energy-and cost-intensive industrial separation processes. Prof. Jing Li and her research group at  Rutgers University have discovered an alternative adsorption-based kinetic separation of propene and propane. They demonstrate, for the first time, that zeolite-like microporous metal organic frameworks (MMOFs) are capable of separating these two hydro-carbon species based on the significant difference in their diffusion rates (125:1). 

Chemical and petrochemical industry

This method is expected to be less expensive and more energy efficient than previous methods.
