Experimental Analysis of Low Viscosity Industrial Oily Waste Energetic Recovery

Abstract

This paper presents an experimental investigation on industrial lubricants transformation to synthetic fuels and their use in a direct diesel diesel engine. Catalytic extraction was achieved using methanol and potassium hydroxide. Industrial oils are mainly pumps lubricant Tiska 32, compressors lubricant Torba 32 and turbines lubricant Torada 32. Biofuel extracted from waste cooking oil and conventional diesel fuel are taken for comparison. Density, viscosity, acidity and flash point of biofuel, synthetic fuels and their blends are measured and discussed. Gas chromatography associated to mass spectroscopy have been done to determine synthetic fuels and the biofuel chemical composition. The use of blends with diesel fuel seems to be required. Three ratios of 15%, 30% and 45% of synthetic fuels and biofuel are tested on a direct-injection diesel engine in order to compare performances, fuel consumption and emissions obtained when the engine is powered with conventionnel diesel fuel, biofuel and synthetic fuels.
