ABSTRACT:
Diamondoid compounds are concentrated in a solvent mixture containing at least 20% by weight of normal and slightly branched C.sub.5 -C.sub.30 paraffins by selectively converting the paraffins to lower boiling aliphatic hydrocarbons and separating the lower boiling aliphatics from the solvent mixture to yield a concentrated solvent mixture enriched in diamondoid compounds. Useful shape selective catalysts include zeolites having Constraint Indices from about 1 to about 12, such as ZSM-5 and MCM-22.
