Abstract
This study provides an environmentally friendly process for the production of waste tire pyrolytic oil from fast pyrolysis for use in lube oil production. The produced waste tire pyrolytic oil was further distilled to provide an almost pure base fluid for production of lube oil. The distilled pyrolytic oil was further transformed to lube oil via polyol synthesis. Characterization of the distilled pyrolytic oil from waste tire pyrolysis shows that the oil after distillation contained 2.04 g/100 g of Aliphatic hydrocarbons, 1.96 g/100 g of naphthalene, and 5.99 g/100 g of paraffin. The synthetic base fluid was blended with additive to obtain the desired lube oil. Based on the results obtained, the properties of the produced lubricant fall within the acceptable criteria for standard lube oils/commercial lubricants. Six different blends (A–F) were produced using varied percentages of the selected additives and the base fluid, however, sample C gave the best lube oil blend considering its average density (0.97 kg/L), average viscosity which compares favourably with ISO viscosity (68 mm2/s) of class 68 oil at 40 °C with a flash point above 200 °C.
