Embodiment 1
[0047] Such as figure 1In the process shown, the catalyst in the supplementary refining reaction zone is not segmented, but only one catalyst A is used. Hexadecahydropyrene can be obtained, and the yield and purity are shown in Table 4.
Embodiment 2
[0049] The hydrofinishing and hydrocracking parts are the same as in Example 1, and only catalyst B is used in the supplementary refining reaction zone. Hexadecahydropyrene can also be obtained, and the yield and purity are shown in Table 4.
Embodiment 3
[0051] The hydrofining and hydrocracking sections are the same as in Example 1, and the supplementary refining reaction zone is divided into two supplementary refining sections, and the gradation scheme of catalyst A and catalyst B is adopted. At the same time, the process conditions are also matched. The product yield and purity are shown in Table 4.
