Embodiment 1
[0043] use figure 1 In the process flow shown, lube base oil is produced by gradation series and mixed process. In Example 1, two hydrogenation reaction zones connected in series are included. In the composite bed of the decondensation cracking catalyst in each reaction zone, the mixing volume ratio of the hydrocracking catalyst to the hydrocracking catalyst is 1:2, and the total amount of catalyst used is Both of Comparative Example 1 and Comparative Example 2 are the same. The hydrocracking catalyst used in Example 1 is FC-50 catalyst, and the hydrodecondensation catalyst is FDW-3 catalyst, both of which are commercial catalysts developed and produced by Fushun Petrochemical Research Institute. The operating conditions and test results are listed in Table 3.
Embodiment 2
[0045] use figure 1 In the process flow shown, lube base oil is produced by gradation series and mixed process. In Example 1, two hydrogenation reaction zones connected in series are included. In the composite bed of the decondensation cracking catalyst in each reaction zone, the mixing volume ratio of the hydrocracking catalyst to the hydrocracking catalyst is 1:2, and the total amount of catalyst used is Both of Comparative Example 1 and Comparative Example 2 are the same. The hydrocracking catalyst used in Example 2 is FC-50G catalyst, and the hydrodecondensation catalyst is FDW-3 catalyst, both of which are commercial catalysts developed and produced by Fushun Petrochemical Research Institute. The operating conditions and test results are listed in Table 3.
