We present experimental data obtained on an example crude oil (21{sm_bullet}API gravity) to illustrate the relation between boiling point and molecular weight of crude oil fractions. We utilize the earlier developed approach for {open_quotes}heavy{close_quotes} crudes characterization to describe the entire crude oil, including a truly nondistillable residue, in terms of the atmospheric equivalent boiling point (AEBP) distribution curve. We demonstrate the application of high temperature gas chromatography simulated distillation (HTGC-SIMDIS) and field ionization mass spectrometry (FIMS) to direct measurements of the AEBP and molecular weight distribution of the {open_quotes}heavy{close_quotes} crude oil fractions. We focus our discussion on the compositional changes with the increasing AEBP and their effect on the molecular weight distribution of the fractions.
