Abstract

The aim of this study is to investigate the possible use of ionic liquids to remove the sulfur from the oil produced through the pyrolysis of waste tyres. This study also focuses on the selection of the type of ionic liquid used to obtain the best sulfur removal, particularly, dibenzothiophene. Liquid-liquid extraction was the preferred method in this study followed by an analysis using the analytical instrument Total Sulfur Analyzer. The ionic liquids that are considered to be the best is 1-butyl-1- methylpyrrolidinium dicyanamide [bmPYR][DCA]. The two parameters that were tested in this project are stirring period of mixture of pyrolytic oil and the ionic liquid and the temperature of the water bath at which the mixture was stirred in. The highest percentage of removal of sulfur was around 75% when the mixture of oil and ionic liquid was stirred at 40°C for 6 hours. From this project, it has been found that for efficient removal of sulfur, the stirring period has to be long enough for the ionic liquid to react completely with the pyrolytic oil and also the temperature at which the mixture was stirred should also be low.!
