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

The reaction of Os 3 (CO) 10 (MeCN) 2 with 18β-glycyrrhetinic acid (18β-GA) yielded the complex [Os 3 (μ-H)(μ-O 2 C C 29 H 45 O 2 )(CO) 10 ] ( 1 ). An X-ray study of the complex indicated that the carboxylated group of 18β-GA is coordinated

The influence of the concentration and type of paraffinic crude oil components on the wax appearance temperature (WAT) was evaluated by means of Polarized Light Microscopy. High pour point waxy crudes were doped with paraffin distillation cuts, and c

Isolation of very large alkane components as described in the first paper within this series, fail in some cases. This work describes two non-routine isolation procedures applied to two different non-typical petroleum fractions. The first one compris

The effect of paraffin class-types on the wax crystallization tendency in oils and the activity of paraffin inhibitors was studied for waxy crude oils. Oils enrichment with isolated paraffin fractions allowed the assessment of the influence of their

Several commercial paraffin inhibitors were evaluated with highly paraffinic crudes. Pour point depression was observed in some of the studied crudes in the presence of any product, while others showed insignificant changes in this parameter. Crudes
