The Properties of Asphaltenes and Their Interaction with Amphiphiles
, 2015 The functional groups on asphaltene surfaces of two kinds of Chinese residue oil were analyzed by X-ray photoelectron spectroscopy (XPS). The ζ potential and electrophoretic mobility of asphaltene solutions and residue solutions were measured through ...

Probing Asphaltenes Aggregation with Fluorescence Techniques [PDF]
, 2014 Asphaltenes correspond to the fraction of oil that is insoluble in heptane but is soluble in toluene. The aggregates of asphaltene are of interest because they cause serious problems in the production of oil.

The composition and thermal properties of waxes in oil asphaltenes
, 2020 © 2015 Akadémiai Kiadó, Budapest, Hungary. Asphaltenes of four Russian and Kyrgyzstan crude oils were investigated with calorimetry, gas chromatography and X-ray diffraction analysis. It was established that asphaltenes contain waxes.
