Embodiment 1
[0075] This example is used to illustrate the method for producing lubricating base oil of the present invention.
[0076] According to the conditions of the first hydrogenation pre-refining, the second hydrogenation pre-refining, hydroisomerization and post-hydrogenation refining listed in Table 2, use the minus three and minus four distillate mixed fractions in Table 1 (weight ratio is 1 : 3) To produce lubricating base oil with Fischer-Tropsch synthetic oil, the mixed fraction of the raw oil minus three and minus four distillates: the weight ratio of Fischer-Tropsch synthetic oil = 1:2, see the properties and yield of the obtained lubricating base oil table 3.
[0077] Among them, the first pre-refined catalyst is ICR-134KAQ (Chevron, USA), the second pre-refined catalyst is Ni containing 10% by weight based on NiO; the protective agent is RGC-1; in the isomerization zone, the first catalyst The layer is a precious metal hydroisomerization catalyst containing Y-type molecular s...
Embodiment 2
[0086] This example is used to illustrate the method for producing lubricating base oil of the present invention.
[0087] According to the conditions of the first hydrogenation pre-refining, the second hydrogenation pre-refining, hydroisomerization and post-hydrogenation refining listed in Table 5, the lubricating base oil is produced from the reduced four distillate and Fischer-Tropsch synthetic oil in Table 4 , Minus four fractions in the raw oil: Fischer-Tropsch synthetic oil = 2:1 (weight ratio), the properties and yield of the obtained lubricating base oil are shown in Table 6.
[0088] Among them, the first pre-refined catalyst, protective agent, and refined catalyst after hydrogenation are all the same as in Example 1. The second pre-refined catalyst contains Co 2 O 3 The first catalyst bed is a precious metal hydroisomerization catalyst containing Y-type molecular sieve. Based on the total weight of the catalyst, the Pt content is 5% by weight, and the Y-type molecular sie...
Embodiment 3
[0097] This example is used to illustrate the method for producing lubricating base oil of the present invention.
[0098] According to the conditions of the first hydrogenation pre-refining, the second hydrogenation pre-refining, hydroisomerization and post-hydrogenation refining listed in Table 8, the lubricating oil base oil is produced from the reduced four distillate and Fischer-Tropsch synthetic oil in Table 7 , The minus four fractions in the raw oil: Fischer-Tropsch synthetic oil = 1:1 (weight ratio), the properties and yield of the obtained lubricating base oil are shown in Table 9.
[0099] Among them, the first pre-refined catalyst, protective agent, and refined catalyst after hydrogenation are all the same as in Example 1. The second pre-refined catalyst contains 20 wt% Ni based on NiO; the first catalyst bed is a precious metal hydroisomerization catalyst containing Y-type molecular sieve. Based on the total weight of the catalyst, the Pd content is 2 wt% The content ...
