The Influence of Paraffinic Base Oil on Low-temperature Viscosity of Naphthenic Base Oil

Low-temperature viscosity of lube oils mixed with paraffinic base oil and naphthenic base oil at different mass ratios has been tested by experiments. The influence of paraffinic base oil on the performance of naphthenic base oil was investigated by studying the low-temperature viscosity of tested oils. The viscosity of lube oils increased with an increasing content of high-viscosity paraffinic base oil in the oil mixture. And the low-temperature viscosity was less influenced when the content of paraffinic base oil in the mixture was insignificant. In order to reduce the cost for formulating lubricating oil, a small fraction of paraffinic base oil can be added into naphthenic base oil as far as the property of lubricating oil can meet the specification. According to the study on low-temperature viscosity of the oil mixed with paraffinic base oil and naphthenic base oil, a basic rule was worked out for the preparation of qualified lubricating oils.

Discoloration of Hydrotreated Naphthenic Rubber Base Oil at High Temperature

In this article, the reasons for discoloration of hydrotreated naphthenic rubber base oil under high temperature were studied in detail. In order to define compositional factors associated with the color deterioration, firstly liquid-solid chromatography was used to separate hydrotreated naphthenic rubber base oil into five different fractions, i.e., saturates, monoaromatics, diaromatics, polyaromatics, and polars. Then color change of each fraction was evaluated under high temperature. The results of the test indicate that polyaromatics and polars are the main precursor of color and deposits, respectively, and the composition of polyaromatics was characterized by elemental analysis, gas chromatography mass spectrometry (GC-MS) and atmospheric pressure chemical ionization mass spectrometer (APCI/MS).

Separation and Characterization of Naphthenic Acids Contained in Penglai Crude Oil

Abstract

Naphthenic acids were separated from highly acidic Penglai crude oil by aqueous alkaline solution and analyzed by infrared spectrum (IR) and mass spectrum (MS). According to our results, the solution was composed of ethanolamine, alcohol, and water, the ratio being 0.1:7.9:10. When the solution and crude oil (ratio 0.4:1) were stirred at the speed of 300–400 r/min at 50°C for at least 10 min, more than 70% of the naphthenic acids in the crude oil could be removed. IR and MS results confirmed the presence of diversified naphthenic acids in Penglai crude oil and provided relative content information.
