Example Embodiment
[0037] Example 1
[0038] The heavy distillate raw material (see Table 1 for properties, the following examples and comparative examples all use this raw material) and hydrogen are mixed and sequentially enter the hydrofining reactor, hydrocracking reactor and separation system to separate light naphtha, Heavy naphtha, jet fuel fraction, diesel fraction and hydrocracking tail oil. The upper part of the hydrorefining reactor is provided with a bottomed cylinder. The height of the cylinder is 5% of the height of the hydrorefining reactor. The outer diameter is 95% of the inner diameter of the hydrorefining reactor. The bottom and side walls of the cylinder are provided with holes through which the flow can pass. The size of the holes is 5 mesh. The cylinder is filled with hydrorefining catalysts in sequence along the flow direction. A. Hydrorefining catalyst B. The filling volume ratio is 1:5. The properties of the hydrorefining catalyst A are as follows: the amount of infrared aci...
