“…Several molecular reconstruction methods have been developed (Al Halwachi et al, 2012;Allen and Liguras, 1991;Alvarez-Majmutov et al, 2014Boek et al, 2009;Neurock et al, 1994;Peng, 1999;Pyl et al, 2011;Quann and Jaffe, 1992;Sheremata et al, 2004;Zhang, 1999). These methods can be classified into three groups according to the approach used to represent the molecular composition: approach by model molecule, deterministic molecular reconstruction approach, and stochastic molecular reconstruction approach.…”

“…The application of the PDF was extended to the petroleum field by Klein's group (Campbell and Klein, 1997;Neurock et al, 1994;Trauth et al, 1994) based on detailed analysis of heavy fractions done by Boduszynski (Boduszynski, 1988(Boduszynski, , 1987. Boduszynski showed that the structural properties of a petroleum fraction follow statistical distributions when plotted against the Atmospheric Equivalent Boiling Point (AEBP), the molecular weight or the number of carbon atoms.…”

“…They are based on different strategies that depend on the type of feedstocks to rebuild. For the heaviest petroleum fractions (vacuum gas oils, atmospheric residues, vacuum residues), the main approach consists in sampling randomly different statistical distributions of structural blocks which are the basic elements of the molecules present in the mixture after reconstruction [1][2][3][4][5][6][7][8]. For the lightest petroleum cuts (gasolines, kerosenes, gas oils), the majority of the methods is based on a predefined set of compounds which is supposed to be representative of the molecules that are actually present in the fraction under investigation.…”
