Influence of Processing Conditions on the Properties of High Paraffin Oil and Sediment Composition
The influence of ultrasonic treatment, a polymer additive, and their combined effect on the structural and rheological properties of highly paraffinic, low-resin oil and the composition of separated sediments was studied. The oil was processed in an ultrasonic field (field intensity, 6 W/cm2; frequency, 22 kHz; and time, 1–10 min). The sedimentation process was carried out at a medium temperature of 30°C and a cold rod temperature of 5°C. Viscosity–temperature parameters of oil were determined using a Brookfield DV-III ULTRA rotational viscometer. Ultrasonic treatment for 1 min and a polymer additive (0.05 wt %) led to a decrease in the viscosity by a factor of 5 and in pour point by 8°C. The introduction of the additive and the complex effect contributed to changes in the molecular weight distribution of n-alkanes in sediments: a shift of the second distribution maximum to the region of higher molecular weight components and an increase in the concentration of n-alkanes ΣC17H36–C33H68.
期刊介绍：
The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
