Embodiment 1~3
[0043] Embodiment 1~3 all adopts flow process of the present invention, figure 1The combined process flow shown. After the high-aromatic catalytic diesel is heated by the heating furnace, it is mixed with the circulating hydrogen and enters the I hydrofining reaction zone for hydrodesulfurization, polycyclic aromatic hydrocarbon saturation and other reactions; the obtained oil is mixed with the circulating hydrogen and enters the II hydrofining reaction zone for further Hydrodesulfurization reaction, selective reaction of aromatics; the obtained oil enters the separation equipment and is cut into light components and heavy components; the light components and circulating hydrogen are mixed into the hydrogenation upgrading reaction zone for hydrocarbon hydrogenation reaction to generate oil Obtain gas, gasoline fractions and diesel fractions with high cetane number through the separation system; heavy components are mixed with circulating hydrogen and enter the hydroconversion ...
