[0036] This example illustrates that using the method provided by the present invention, the raw material is first cut through the distillation range to obtain the light cycle oil light fraction and the light cycle oil heavy fraction, and the cutting point is 250°C.
[0037] The heavy fraction of light cycle oil enters the medium-sized hydrogenation unit. The hydrogenation test conditions are: hydrogen partial pressure 8.0MPa; average bed reaction temperature 360°C, volumetric space velocity 2.0 hours -1 , The volume ratio of hydrogen to oil is 1100Nm 3 / m 3 . The content of bicyclic aromatic hydrocarbons in the hydrogenated heavy fraction is 9.6% by weight.
[0038] The light fraction of light cycle oil and the heavy fraction of light cycle oil after hydrogenation enter the upper and lower nozzles of the medium-sized catalytic cracking riser reactor respectively. The light fraction enters the lower nozzle and the hydrogenated heavy fraction enters the upper nozzle. The distance be...
