Asphaltene finds a distinguished position in current research on liquid and solid
hydrocarbon fuels due to its self-aggregating nature. The presence of asphaltene in crude …

Asphaltenes are heteroatom rich macromolecules thought to be mainly derived from the
early breaking of covalent bonds in kerogen and thus have been considered to be a lower …

For decades, discussion of asphaltene structure focused primarily on molecular weight. Now
that it is widely accepted that asphaltene monomers are between∼ 250 and 1200 g/mol …

沥青质是石油或岩石可溶有机质的重要组分之一, 通常具有复杂的大分子结构和较高的分子量.
沥青质中包裹(或键合) 的生物标志物被认为具有重要的油气地球化学研究价值 …

Asphaltenes, as the heaviest and most polar fraction of petroleum, have been characterized
by various analytical techniques. A variety of fractionation methods have been carried out to …

The effects of asphaltenes from two heavy oil residues on the sedimentation stability of
residual marine fuels were assessed and compared. As base components of residual …

Asphaltenes are an important class of complex carbon-rich molecules found in crude oil.
Their chemical structure varies depending on the geological source but generally comprises …

Asphaltenes constitute a heavy aromatic crude oil fraction with a propensity to aggregate
and precipitate out of solution during petroleum processing. Aggregation is thought to …

Asphaltene precipitation and deposition in the reservoir, near-wellbore region, and pipelines
is one of the critical problems in flow assurance. It can cause a blockage of pore throats and …

Since 2020, 0.5% limits on the sulfur content of marine fuels have been in effect worldwide.
One way to achieve this value is to mix the residual sulfur and distillate low sulfur …
