This paper presents the study of saturated biomarkers in maltenes and the compounds adsorbed and occluded by the asphaltenes of six Venezuelan crude oils. The study is intended to know to what extent geochemical information stored in the adsorbed and

Retention of alkane compounds on asphaltenes was carried out in organic solutions. The distribution of retained and nonretained alkanes was assessed by GC/MS and interpreted from the perspective of reverse phase liquid chromatography (RPLC). Results

Aggregation of asphaltenes was simulated using a mathematical model based on the following consecutive equilibrium: nA⇄K1An and mA+An⇄K2An+m, where A, An, An+m, K1, K2 represent asphaltenes, n aggregates, n + m aggregates, and equilibrium constan

Asphaltenes are a complex mixture of compounds grouped as the colloidal phase in crude oils. Two fractions, A1 and A2, have been isolated from them. A1 is defined as the mayor and practically insoluble fraction, while A2 has a similar solubility to t
