Molecular size characterization of heavy oil fractions in vacuum and solution by molecular dynamic simulation

Wenpo REN, Honggang CHEN, Chaohe YANG, Honghong SHAN,

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 3,   Pages 250-256 doi: 10.1007/s11705-009-0281-7

Abstract: According to the elemental analysis, molecular weight and H-NMR data, average molecular structures ofconformations of polycyclic aromatic and heavy resin in vacuum and toluene solution were obtained by moleculardynamic simulation, and the molecular size was gotten via the radius of gyration analysis.With molecular weight increasing, the molecular size in vacuum and toluene solution also increased.Thus, the molecular size in toluene solution was larger than that in vacuum.
