example 1
[0033]According to the process shown in FIG. 4, the experimental device and the feed stock were the same as those in Comparative Example 1. The other reaction conditions were the same as those in Comparative Example 1 except that the reaction temperature of isomerization / asymmetrical cracking was 351° C., and the space velocity was 0.75 h−1. The reaction conditions of Comparative Example 1 are shown in Table 3.
[0034]Product distribution comparison of Example 1 and Comparative Example 1 is shown in Table 4, and main product properties are shown in Table 5.
[0035]According to the process shown in FIG. 4, paraffin base 200SN lightly dewaxed oil was used as a feed stock in the experimental device of Comparative Example 1, and the physical and chemical properties of the feed stock are shown in Table 2. The reaction conditions are shown in Table 3.

example 2
[0038]The process, experimental device and feed stock were the same as those in Comparative Example 2. The other reaction conditions were the same as those in Comparative Example 2 except that the temperature of the isomerization / asymmetrical cracking reaction was 325° C., and the liquid hourly space velocity was 1.2 h−1.
[0039]The product distributions of the reactions of Example 2 and Comparative Example 2 are shown in Table 8, and main properties of the products are shown in Table 9.
[0040]It can be seen from Tables 6 to 9 and FIG. 2 that compared with Comparative Example 2, the method of Example 2 has significant features of a hydrorefining-isomerization / asymmetrical cracking-hydrofinishing, that is, the yield of a heavy base oil (5 cst base oil) is high, and the yields of small-molecule products (gas and naphtha) and big-molecule products (10 cst base oil) are both high, and are up to 19.96% and 73.3% respectively, the yields of diesel oil and a light base oil (2 cst base oil) ar...
example 3
[0041]According to the process shown in FIG. 4, the experimental device is the same as that in Comparative Example 1, and the feed stock is a 100N cerate obtained from crude oil by processes of reduced-pressure distillation, furfural refining and acetone-toluene dewaxing, of which the physical and chemical properties are shown in Table 10. Under the process conditions shown in Table 11, the resulting product distribution is shown in Table 12, and the main properties of the products are shown in Table 13.
