Doping of Petroleum, Oil and Lubricants with Carbon Nanotubes as a Way to Improve the Performance of POL
It is assumed that carbon nanotubes can be used as an additive, which will improve the operational properties and functional characteristics of lubricants. The doping of petroleum, oil and lubricants – semi – synthetic engine oil – with the carbon nanotubes, taken in various wt.% of additives, was carried out: 0.01; 0.1; 0.5 wt.%. The following physical and chemical characteristics were investigated: 1) viscosity of composite mix at a temperature of T = 25 °C (an initial state); 2) viscosity of composite mix after its aging at T = 160 °C on the mode of oxidation of the investigated samples of composite mix during 24 h; 3) the oxidation stability has been determined by the «acidity» and «acid number» parameters, these parameters have been carried out for the investigated samples of composite mix in an initial state and after aging. We assumed that doping of oil with carbon nanotubes will change some of oil’s properties such as an indicator of viscosity, and chemical stability. The way of development functional and operational characteristics of lubricants by doping with carbon nanotubes was suggested. Results of researches showed that doping of carbon nanotubes causes change of such physical and chemical characteristics of lubricant as viscosity, acidity and acid number, alkaline parameter. Doping of lubricant with carbon nanotubes stops oxidation process and also leads to decrease of acidity and acid number in an initial state and for a state after aging. Besides, the carbon nanotube’s presence has increased alkaline parameter after aging of composite mix that provides ability of oil to neutralize collateral sulphurous products and after aging during its exploitation. Thus, the researches proved positive influence of carbon nanotubes on the main functional characteristics of lubricants that allow us to recommend CNTs as new additives of liquid lubricant composite mixes.
