Propane/Propene separation by selective adsorption on porous coordination polymers(Abstract)

摘要

The state-of-the-art procedure for the separation of propane/propene mixtures is via fractional distillation. This is one of the most energy-intensive separations performed industrially and difficult to accomplish due to the very similar boiling points of the alkane (-42.1 A°C) and the alkene (-47.4 A°C). The required low temperatures and pressures above one bar make this distillation so energy consuming.
