Annual Review of Analytical Chemistry, 2011 Asphaltenes, the most aromatic of the heaviest components of crude oil, are critical to all aspects of petroleum utilization, including reservoir characterization, production, transportation, refining, upgrading, paving, and coating materials. The asphaltenes, which are solid, have or impart crucial and often deleterious attributes in fluids such as ...

Interfacial behavior of asphaltenes
Advances in Colloid and Interface Science, 2016We review the existing literature on asphaltenes at various types of interfaces: oil-water, air-water, gas-oil and solid-liquid, with more emphasis on the oil-water interfaces. We address the role of asphaltene aggregation, recently clarified for asphaltenes in bulk by the Yen-Mullins model.

Model molecules mimicking asphaltenes [PDF]
Advances in Colloid and Interface Science, 2015 Asphalthenes are typically defined as the fraction of petroleum insoluble in n-alkanes (typically heptane, but also hexane or pentane) but soluble in toluene.

ADSORPTION OF ASPHALTENE FUNTIONALITIES AND ASPHALTENE ON GOETHTTE
Fuel Science and Technology International, 1995ABSTRACT Solid-stabilized water-in-oil emulsions cause many problems such as oil loss, fouling of a processing unit, and environmental hazard in the petroleum production and refining. The ability of finely divided solids to stabilize these emulsions is due to the adsorption of asphaltenes and other heavy constituents. This study presents the individual

Study on inhibition behaviors of asphaltene inhibitor to asphaltene aggregations
Journal of Dispersion Science and Technology, 2021The changes in the stability of asphaltene in crude oil will give rise to its aggregation, coalescence and deposition from crude oil.

Solution Properties of Asphaltenes
Langmuir, 2008Ultracentrifugation has been used to produce asphaltene fractions of reduced polydispersity. The structure of these asphaltene fraction solutions has been investigated using viscosity and X-ray scattering (SAXS) measurements as a function of concentration.

One of the major problems encountered during the exploitation of the oil reservoir is the deposition of asphaltene in the porous rock near the wellbore. The crude oil asphaltene considerably reduces the rock permeability and, consequently, the oil production.

Effects of asphaltene concentration and asphaltene agglomeration on viscosity
Fuel, 2019Abstract Asphalenes are regarded as the most polar and heaviest components in crude oil system. Their precipitation and agglomeration cause problems in oil recovery, production, and transportation. Asphaltenes are directly responsible for determining the viscosity of crude oil.
