Embodiment 1
[0016] Embodiment 1 Take 70 grams of catalytic cracking oil slurry, 35 grams of ethylene tar, and carry out purification treatment under the condition of 60 ° C. After mixing, add a solvent. In this example, C9 solvent oil is added to dilute, and the filtrate is filtered, and the filtrate is added to the autoclave, and the temperature is 260°C, reacted for 6 hours, and the reaction pressure was 3.5MPa to obtain the reaction solution. After refining and removing impurities, the target impregnated bitumen product was obtained. The indicators of the received bitumen product are shown in Table 1.
Embodiment 2
[0017] Example 2 Take 70 grams of catalytic cracking oil slurry, 30 grams of ethylene tar, and carry out purification treatment at 80 ° C. After mixing, add a solvent. In this example, add C9 solvent oil for dilution, filter to obtain a filtrate, take the filtrate and add it to an autoclave, and experiment The preferred temperature is 360°C, the reaction is 6 hours, and the reaction pressure is 3.5MPa. After the reaction, the reaction liquid is obtained, and the target impregnated asphalt product is obtained after refining and removing impurities. The received asphalt product indicators are shown in Table 1.
Embodiment 3
[0018] Example 3 Take 60 grams of catalytic cracking oil slurry, 40 grams of ethylene tar, and carry out purification treatment under the condition of 100 ° C. After mixing, add a solvent. In this example, add C10 solvent oil for dilution, and filter to obtain a filtrate. Take the filtrate and add it to an autoclave. 460°C, reacted for 8 hours, and the reaction pressure was 3.5MPa to obtain the reaction solution, and the target impregnated bitumen product was obtained after refining and removing impurities. The indicators of the received bitumen product are shown in Table 1.
