Abstract

Ultrasonic treatment (UST) of a 30 wt % heavy oil emulsion of distilled water was shown to depress the water droplet dispersion, emulsion viscosity, and the specific fracture energy of the dispersed system. The interfacial layer extracted from the sonicated emulsion had a lower content of resins and a higher content of asphaltenes than the interfacial layer of the initial emulsion. After the UST, the resins of the interfacial layer exhibited a higher concentration of oxygenated moieties, and the average asphaltene molecule had a lower number of sulfur, oxygen, and carbon atoms in its aliphatic moieties.

超声处理对高粘度油乳剂性能及界面组成的影响

超声波处理（UST）的30 wt %的蒸馏水重油乳液被证明可以降低水滴分散，乳液粘度和分散体系的比破裂能。超声乳化液中提取的界面层树脂含量较低，沥青质含量较高。在UST之后，界面层的树脂表现出更高浓度的含氧部分，而沥青质分子在其脂肪族部分中平均具有更低数量的硫、氧和碳原子。

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
