Abstract:
Conventional base oils are obtained separating undesirable compounds by physical processes, and their quality depends on the quality of petroleum. These oils have higher amount of aromatic hydrocarbons and sulfur compounds and have worse physico-chemical characteristics of base oils obtained with modern techniques. The final treatment of these oils can be made by hydrogen or active aluminosilicate clay. In this paper was investigated the effect modified bentonite by acid from the site Šipovo on content of aromatics and some physico-chemical characteristics (viscosity, index of viscosity, index of refractive, color, density and demulsibility) of sample on base oil. Contens of aromatics was determined by IR spectroskopy (IR) and UV spectrophotometry (UV). The results of investigation showed that there is a slight reduction in aromatic content and change of tested physico-chemical characteristics, and realized effects of processing tested oil by acid are similar effects processing by activated clay.

Key words:
modified bentonite, content of aromatics, physico-chemical characteristics, convencional base oils
