heal.abstract	Light cycle oil (LCO), an oil product containing valuable light and aromatic hydrocarbons, can have the characteristics of a good diesel fuel blending component, if first has been upgraded. In the context of ongoing research towards a better LCO quality, the focus is on how the extraction of LCO is affected by solvent, temperature and solvent to feed ratio variation. The solvents used were acetonitrile (ACN) and its water and methanol mixtures. The pure ACN system was extracted at 40, 50, 60 and 70°C, in 1, 1.5, and 2.5 solvent to feed ratios. The efficiencies of the extractions were evaluated by comparing the yield of the extracted products (raffinate and extract) and their heteroatom content (S and N). The compositional analysis of the extraction products was assessed by gas chromatography-mass spectrometry (GC-MS) and Fourier transform infrared spectroscopy (FT-IR). The yield of raffinate product found to increase with increased water content in the solvent, while it was invariant in the presence of MeOH. FT-IR analysis showed a more pronounced effect by the solvent to feed ratio increase than the temperature effect towards a better raffinate quality, verified by the yields and the densities of the raffinates. GC-MS analysis data confirmed the latter, were the distribution patterns of hydrocarbons and aromatics in the raffinate product showed increase of the n-alkanes and decrease of the aromatic compounds as the solvent to feed ratio increased. The extraction process can be optimized in order to achieve the highest possible raffinate yield with satisfactory properties.	en
