The sorption in nano-sized, mesoscopically structured ZSM-5 occurs via a weakly bound physisorbed state at the external surface, which concentration is the crucial parameter for the selective sorption enhancement. The general mechanism doesn’t change upon addition of a second molecule, but a strong retardation of the bulkier co-sorbate occurs. However, retaining the transport properties in formed particles is difficult due to additional transport resistance within the newly formed meso- and macropores.
