摘要：

The light cycle oil (LCO) produced after the secondary cracking is rich in polycyclic aromatic hydrocarbons, which is challenging to be used as a blending component of automotive diesel fuel even after hydrofining. To improve the added value of LCO, a combined process of hydrofining, fractionating, and solvent extraction was proposed. The process first hydrotreated LCO to saturate the bi- and tricyclic aromatic hydrocarbons. Then the generated hydrogenated LCO was cut into the light fraction, which was used as fluid catalytic cracking (FCC) feedstock, and heavy fraction, which was used to produce diesel fuel and chemical raw materials by solvent extraction. The process combines the conventional devices in the refinery and is an effective technology for processing and utilizing LCO.
