摘要：

With the excess domestic diesel output and low gasoline demand, reducing the diesel-to-gasoline ratio and increasing the production of chemical products have become the preferred transformation route for refineries. In this work, based on the molecular structure, HCO was selectively hydrogenated to convert PAHs to crackable components, which were then cracked in an FCC unit. According to market demand, flexible adjustment between light oil and chemical feeds could be made. After selective hydrogenation of HCO, FCC conversion rate is up to 60.14%(mass ratio), and the yield of gasoline and diesel increased 19.16%(mass ratio) and 6.50%(mass ratio) from HCO, respectively. The total aromatics in gasoline is 56.8%(mass ratio), of which triphenyl is 21.3%(mass ratio), about 37% of the total aromatics. Moreover, the yields of heavy oil and coke decrease significantly. © 2022 Chemical Industry Press. All rights reserved.
