Liquid–Liquid-Phase Equilibrium for Quaternary Systems (n-Decane + 1-Tetradecene + 1-Methylnaphthalene + Sulfolane/Dimethyl Sulfoxide) for Separation of 1-Methylnaphthalene from FCC Diesel

Clean utilization of catalytically cracked diesel is of paramount importance in the industry. The separation of polycyclic aromatic hydrocarbons (PAHs) from catalytically cracked diesel can significantly reduce the content of aromatics and increase the cetane number to improve the quality of diesel. In this work, for extracting the PAH 1-methylnaphthalene from the model fluid catalytic cracking diesel, the liquid–liquid equilibrium phase...
