Hydrocarbon molecules with a carbon ring structure similar to aromatics. Naphthenes have saturated bonds rather than the unsaturated ones which characterize aromatics. Reformers make aromatics, the high-octane components they intend to produce, most easily by desaturation naphthene rings. The "N" in PONA and N+A stands for naphthenes.
