摘要

摘要用超声波（样品重量 50 g，频率 22 kHz，场强 8 W/cm2）处理高蜡原油 10 分钟。超声波处理导致原油粘度、粘流活化能、分散体系断裂比能、凝结点、倾点和沉淀量增加，沉淀结构也发生了变化。通过红外光谱和色谱-质谱法分析了原油、沉淀物和沥青质的油组分。经超声波处理的原油沉淀物油中的高分子量正构烷烃含量大大降低。

Effect of Ultrasonic Treatment on the Properties and Composition of High-Wax Crude Oil and Its Precipitates

High-wax crude oil was treated with ultrasound (sample weight 50 g, frequency 22 kHz, field intensity 8 W/cm²) for 10 min. The ultrasonic treatment led to an increase in the crude oil viscosity, viscous flow activation energy, specific energy of the break of the disperse system, congealing point, pour point, and precipitate amount and to changes in the precipitate structure. The oil fraction of the crude oil, precipitates, and raffinates was analyzed by IR spectroscopy and chromatography–mass spectrometry. The content of high-molecular-mass n-alkanes in oils from the precipitate of the ultrasonically treated crude oil considerably decreases.

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.
