used oil - Opis:
- This publication concerns the influence of the oxidation process on oil properties. The work contains a description of the properties and production of naphthenic oils and processes related to the exploitation of oils. This topic is really interesting in view of the ongoing development of technology and the automotive industry, and the importance of regeneration of used oils. Two types of oils were used in the tests: T22 – naphthenic oil and N100 – oil obtained from regeneration of used oils. The consistency and structure of used oils are strongly connected to the degree to which it has been used, the original sources of individual basic oil components, physicochemical changes, and also the amount of contaminants. The level of toxicity depends on the environmental conditions, adaption time and on the method and conditions of collection. The longer the oil is used, the more toxic it becomes. The research examined the oxidation resistance of these oils and their mixtures and also the effectiveness of the inhibitors’ function in these oils. In this research, the function of inhibitor effectiveness was confirmed. After addition of antioxidant to the examined oils and mixtures, their level of resistance increases. These oils were tested for stickiness, sulphur content, density and acidity. Naphthenic oil was more resistant than the oil obtained from the regeneration process of used oils. Antioxidants are effective in both oils. The addition of an amine antioxidant was more effective than a phenol antioxidant. The concentration of antioxidant had an impact on this process. In case of naphthenic oils, the phenol antioxidant was more effective in a higher concentrations, the amine antioxidant – in lower concentrations. For regenerated oils, the phenol inhibitor was more effective at higher concentrations and the amine antioxidant at lower concentrations. The amount of sulphur in the oil was several tens of times smaller than in naphthenic oil.
