Embodiment 1

[0019] FCC oil slurry was used as raw material, and furfural was used as solvent to carry out liquid-liquid extraction to enrich aromatics. The aromatic components in the FCC oil slurry account for 62.80wt%, and the saturated content is 37.20wt%. The content of aromatics in the components reaches 90.50wt%, and the saturated content is 9.50wt%. The content of aromatics in the aromatic-poor component is 37.20wt%, and the saturated content is 72.80wt%. The derivatives are prepared using aromatic-rich components as raw materials. Take the aromatic-rich component: Br 2 =8:1 (weight ratio), plus FeCl 3 As a catalyst, the added amount accounts for 5.00wt% of the total amount, the maximum reaction temperature is 120° C., and the reaction time is 2 hours to obtain aromatic hydrocarbon brominated derivatives with a yield of 31.00wt%. Add 3 times the weight of 50% NaOH solution to the aromatic brominated derivatives and react at a constant temperature of 70° C. for 1 hour to obtain p...

[0021] FCC oil slurry was enriched with aromatics by liquid-liquid extraction using pyrrolidone as solvent. The aromatic components in the FCC oil slurry accounted for 55.20wt%, and the saturated content was 45.80wt%. After extraction at a temperature of 50°C and a solvent-to-oil ratio of 1:1, aromatic-rich components and aromatic-poor components were obtained. Among them, the aromatic-rich components The content of aromatics in the fraction reached 76.80wt%, and the saturated fraction was 23.20wt%. The content of aromatics in the aromatic-poor component is 28.80wt%, and the saturated content is 71.20wt%. The derivatives are prepared using aromatic-rich components as raw materials. Get aromatic-rich component: HCl=5:1 (weight ratio), add Al 2 o 3 As a catalyst, the added amount accounts for 5.00wt% of the total amount, the maximum reaction temperature is 90°C, and the reaction time is 3 hours to obtain aromatic hydrocarbon chlorinated derivatives with a yield of 31.00wt%. ...

Description

technical field [0001] The invention relates to a preparation method of condensed polycyclic polynuclear aromatic hydrocarbon resin, especially using polycyclic aromatic hydrocarbons in petroleum or coal tar as raw materials, and adopting a method for preparing polycyclic aromatic hydrocarbon derivatives to prepare high heat-resistant, high-strength condensation resins. Method for polycyclic polynuclear aromatic hydrocarbon resins. Background technique [0002] Petroleum is a non-renewable resource and is facing the danger of depletion. The problem of how to make full use of existing petroleum resources to develop new high value-added chemical materials is becoming increasingly prominent. As crude oil becomes heavier and heavier, residual oil with a boiling point greater than 500°C has accounted for about 40% of the total crude oil in the world, and even more than 50% in China. The annual output of residual oil in my country can reach 60 million to 70 million tons. However...
