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. The 360-520°C fraction is obtained by cutting the fraction, and the 360-520°C fraction is obtained through hydrogenation and furfural production process. The operating parameters of each production process are shown in Table 4 and Table 5. The properties of the hydrogenation catalyst are shown in Table 6. The aromatic content of each fraction is shown in Table 7.
Embodiment 2
[0016] Using crude oil B as the 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 360-520°C fraction is obtained by cutting the fraction, and the 360-520°C fraction is obtained through hydrogenation and furfural production process. The operating parameters of each production process are shown in Table 4 and Table 5. The properties of the hydrogenation catalyst are shown in Table 6. The aromatic content of each fraction is shown in Table 7.
Embodiment 3
[0018] 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. Cut the fraction to obtain a 360-520°C fraction, and the fraction is subjected to hydrogenation and furfural production processes to obtain a 360-20°C fraction. The operating parameters of each production process are shown in Table 4 and Table 5. The properties of the hydrogenation catalyst are shown in Table 6. The aromatic content of each fraction is shown in Table 7.
