Geological and Geochemical Characteristics of the First Member of the Cretaceous Qingshankou Formation in the Qijia Sag, Northern Songliao Basin, Northeast China: Implication for I... by Fei Xiao, Jianguo Yang, Shichao Li, Fanhao Gong, Jian Zhang, Yulai Yao, Ang Li, Liyan Zhang, Yiming Huang, Fei Su, Yunfeng Bai

“…The saturated hydrocarbon of EOM (extractable organic matter) in K2qn12 and K2qn13 is of higher content than that in K2qn11, while it is the opposite for the aromatic hydrocarbon, nonhydrocarbon, and asphaltene, indicating better oil mobility for K2qn12 and K2qn13. …”

Study on Colloidal Model of Petroleum Residues through the Attraction Potential between Colloids by Long-li Zhang, Guo-hua Yang, Chao-he Yang, Guo-he Que

“…It was assumed that the cores of colloidal particles were formed by asphaltenes and heavy resins mainly; the other fractions acted as dispersion medium. …”

Bioremediation of Oil-Contaminated Soils of the Zhanazhol Deposit from West Kazakhstan by Pseudomonas mendocina H-3 by Yerlan Doszhanov, Aitugan Sabitov, Zulkhair Mansurov, Gulzhan Kaiyrmanova

“…Six and twelve months after the treatment of the oil-contaminated field with microorganisms, the amount of oil fractions in the soil decreased noticeably, while the content of asphaltenes remained constant. Analyses show that the composition of the oil fraction changes—the concentration of paraffin-naphthenic—polycycloaromatic components decreases, whereas the relative amount of mono- and bicycloaromatic hydrocarbons increases. …”

Investigations of the Montmorillonite and Aluminium Trihydrate Addition Effects on the Ignitability and Thermal Stability of Asphalt by Kai Zhu, Ke Wu, Bin Wu, Zhiyi Huang

“…TGA tests had indicated that the montmorillonite (MMT and OMMT) could suppress the release of flammable volatiles and form more asphaltenes, which hence postponed the burnout time of asphalt. …”

Toxicity of Flare and Crude Hydrocarbon Mixtures by Sonja V. Cook, Angus Chu, Ron Goodman

“…This lack of partitioning appears to be related to the relatively high concentrations of asphaltenes and polar compounds in the flare pit whole mixture.…”

Influence of the Chemical Composition of Asphalt and the 3D Morphology of the Aggregate on Contact Surface Adhesion by Luoke Li, Meng Guo, Cong Zeng

“…Alkaline limestone aggregates should be used with asphalt with a high aggregate content of colloid and asphaltenes. Basalt aggregate with weak alkalinity should be used with asphalt with a high colloid content, and the use of angular aggregates should be avoided. …”

Microstructural modifications in bitumens rejuvenated by oil from pyrolysis of waste tires by Michela Alfe, Valentina Gargiulo, Giovanna Ruoppolo, Francesco Cammarota, Pietro Calandra, Cesare Oliviero Rossi, Valeria Loise, Michele Porto, Roberto Di Capua, Paolino Caputo

“…The blends were also investigated using atomic force microscopy, and the asphaltenic fraction was assessed via optical microscopy.Results and discussionAll the data consistently indicate that oil addition not only reduces the viscosity of bitumen and restores it to values close to the original unaged bitumen but also changes the intermolecular structure to recover the self-assembly pattern typical of the unaged sample. …”

The Oil-Bearing Strata of Permian Deposits of the Ashal’cha Oil Field Depending on the Content, Composition, and Thermal Effects of Organic Matter Oxidation in the Rocks by Galina P. Kayukova, Anastasiya N. Mikhailova, Igor P. Kosachev, Dmitry A. Emelyanov, Mikhail A. Varfolomeev, Boris V. Uspensky, Alexey V. Vakhin

“…These processes lead to a decrease in the amount of OM in the rocks and an increase in the content of resins and asphaltenes in the oil extracted from them, as well as an increase in the viscosity of the oil. …”
