Embodiment 1
[0014] Using crude oil A as raw material, whose properties are shown in Table 1, a thermal cracking process was carried out, and the operating conditions of the thermal cracking process are shown in Table 3. Cutting the fraction to obtain a 360-520°C fraction, which is subjected to a hydrogenation production process to obtain a 360-520°C fraction. The operating parameters of each production process are shown in Table 4. The properties of the hydrogenation catalyst are shown in Table 5, and the aromatic hydrocarbon content values of each fraction are shown in Table 6.
Embodiment 2
[0015] Example 2: Using crude oil B as raw material, the properties are shown in Table 1, a thermal cracking process is carried out, and the operating conditions of the thermal cracking process are shown in Table 3. The fraction of 360-520°C is obtained by cutting the fraction, and the fraction of 360-520°C is obtained through the hydrogenation production process. The operating parameters of each production process are shown in Table 4. The properties of the hydrogenation catalyst are shown in Table 5, and the aromatic hydrocarbon content values of each fraction are shown in Table 6.
Embodiment 3
[0017] Using crude oil C as raw material, whose properties are shown in Table 1, a thermal cracking process was carried out, and the operating conditions of the thermal cracking process are shown in Table 3. The fraction of 360-520°C is obtained by cutting the fraction, and the fraction of 360-520°C is obtained through the hydrogenation production process. The operating parameters of each production process are shown in Table 4. The properties of the hydrogenation catalyst are shown in Table 5, and the aromatic hydrocarbon content values of each fraction are shown in Table 6.
