ABSTRACT:
A process for the separation of 2,7 DIPN from a hydrocarbon feed mixture comprising 2,7 DIPN and one or more other DIPN isomers, which process employs an adsorbent, comprising a type Y zeolite, dried to an LOI less than 10% which has been at least partially cation exchanged, at exchangeable sites, with potassium. The 2,7 DIPN thereafter is removed from the adsorbent by contacting it with a desorbent material, comprising toluene, at desorbent conditions, and is recovered as an extract product stream. In a preferred embodiment, the process uses a simulated moving-bed countercurrent flow system.
