Abstract:
Para-xylene is separated from a mixture of C8 aromatics using a simulated moving bed (SMB) adsorption process, wherein a MOF is used as an adsorbent and an alkane or alkene having 7 or less carbon atoms, such as hexane or heptane is used as desorbent. Because of the difference in boiling points of a hexane or heptane desorbent as compared to conventional desorbents such as toluene or para-diethylbenzene, less energy is required to separate hexane or heptane from C8 aromatics by distillation than the energy required to separate toluene or diethylbenzene from C8 aromatics by distillation.

Claim (Index 9):
The process of  claim 7 , wherein the bottoms stream from step (h) comprises at least a portion of the C7- alkane or alkene introduced into the distillation zone of step (h);\n wherein the isomerization zone of step (k) is maintained under vapor phase conditions; and wherein C7- alkane or alkene is cracked in the isomerization zone of step (k).
