The work herein presents a novel ultrasound-assisted sequential extraction (UASE) method
for fractionating bio-oils derived from lignocellulosic biomass pyrolysis. The fractionation …

The deposition of asphaltenes in the petroleum industry has been found to be a significant
factor affecting the profitability of petroleum production and refining. For this reason, many …

The aggregation and adsorption of asphaltenes in dilute solutions has been extensively
studied and is now well established. At low concentrations, asphaltenes are mainly found in …

In the present work, the first data on the adsorption behavior of petroleum vanadyl
porphyrins in the presence and absence of asphaltenes are afforded. As adsorptives, N, N …

The scientific petroleum community now recognizes that island-and archipelago-type
molecules coexist in the asphaltene fraction of crude oils and that their relative abundance …

The presence of asphaltenes in crude oil is a key factor in stabilizing water-in-oil emulsions.
Changes in asphaltene aggregation have a definite effect on the formation of an elastic and …

Asphaltene elution behavior in gel permeation chromatography (GPC) was studied with and
without the presence of silver triflate (AgOTf) via inductively coupled plasma mass …

Asphaltenes, which are the most polar components found in crude oil, pose numerous
challenges to the oil industry, during production, transport, and refining operations. In order …

Asphaltene deposition phenomenon is a challenging event that may occur during the oil
