                           Figure 14.1 The number of possible hydrocarbon isomers of fractions with up to 20 carbon
                           atoms in oil fractions: ————, paraffins; – – – – –, naphthenes; . ....., mono-olefins; —
                             —  , aromatics.




                           the details of these developments has been kept inside the walls of the research insti-
                           tutes and have never been reported in the open literature.
                             Since the boiling range of a petroleum fraction is its main characteristic and the
                           fractions are generally designated according to these boiling ranges, this present
                           chapter will be divided into sections according to boiling range.
