Partridge, R D; Whitehurst, D D

This patent describes a method for concentrating diamondoid compounds in a solvent. It comprises: providing a solvent mixture containing at least 20% by weight of normal or slightly branched paraffins having from 5 to 30 carbon atoms with at least one diamondoid compound dissolved therein; contacting the solvent mixture with a shape-selective catalyst under conversion conditions to convert at least a portion of the normal or slightly branched paraffins to lower boiling aliphatics and to prevent conversion of more than about 10% by weight of the diamondoid compounds; and separating the lower boiling aliphatics from the solvent mixture to yield a concentrated solvent mixture enriched in the diamondoid compound.
