This is then followed by isomerization andhydrogenation.

Conversely, the degree ofhydrogenationcan be very low and in this case the aromatic fraction will grow at the expense of the naphtenic fraction.

Furthermore, they present a certain versatility : their degree ofhydrogenationand hence their aromatic and naphtenic content can change according to the environment where these molecules are present.
