title: Recycling of waste engine oil for diesel production.
abstract: The aim of this work was to recycle waste engine oil until converting it into reusable product, diesel fuel. The waste oil was treated using pyrolytic distillation. The effect of two additives (sodium hydroxide and sodium carbonate) in the purification of the obtained fuel was also studied. Moreover, the influence of the number of distillations were analysed. Some thermal and physicochemical properties (density, viscosity, colour, turbidity, acidity value, distillation curves, cetane number, corrosiveness to Cu, water content, flash point and hydrocarbons) were determined to analyse the quality of the obtained fuel. The best results were obtained with 2% of sodium carbonate and two successive distillations. The obtained results showed that pyrolytic distillation of waste engine oil is an excellent way to produce diesel fuel to be used in engines.
