A Study on the Adsorption and Catalytic Oxidation of Asphaltene onto Nanoparticles [PDF]
Journal of Petroleum Science and Technology, 2017 The use of nanoparticles, including metal oxide surfaces, as asphaltene adsorbents is a potential method of removing and/or upgrading asphaltenes. The adsorption of two asphaltene types, extracted from two types of Iranian crude oil, onto nanoparticles ...

Asphaltenes conversion by chemical modification [PDF]
, 2015 Canadian oilsands bitumen contains one of the highest amounts of asphaltenes (16-20 wt %) among all crude oils. Asphaltenes are the lowest value fraction of bitumen. It differs from the other fractions of bitumen because of its insolubility in paraffinic

Asphaltenes and Asphaltene model compounds: Adsorption, Desorption and Interfacial Rheology. [PDF]
, 2016 There are numerous problems encountered during extraction, production, transportation and refining of crude oil. Most of these problems are typically oil-specific, meaning that they depend upon the source of the oil, and sometimes they are reservoir ...

Asphaltenes at Oil/Gas Interfaces: Foamability Even with No Significant Surface Activity
Colloids and Interfaces, 2018 In the oil industry, oil foams can be found at different steps from the crude oil treatment to the gas stations. Their lifetime can sometimes reach several hours and be much longer than the residence times available for gas/liquid separation.
