example 1
[0087]A feedstock A was prepared by adding dimethylsulfide to a vegetable fat and oil 1 so that the sulfur content (in terms of sulfur atom) is 10 mass ppm. The feedstock A was hydrotreated using the catalyst A shown in Table 1 under the condition a shown in Table 3. The hydrotreated oil was isomerized using the catalyst B shown in Table 1 under the condition b shown in Table 3. A fraction having a boiling range of 140 to 280° C. obtained from the isomerized oil after isomerization was used as a base 1. The properties of the base 1 are shown in Table 4. An aviation fuel oil composition 1 was prepared by mixing the base 1 with 30 vol % of a catalytic cracking kerosene having the properties shown in Table 2 obtained from a fluid catalytic cracking apparatus.
example 2
[0088]A feedstock B was prepared by adding dimethylsulfide to a vegetable fat and oil 2 having the properties shown in Table 2 so that the sulfur content (in terms of sulfur atom) is 10 mass ppm. The feedstock B was hydrotreated using the catalyst A shown in Table 1 under the condition c shown in Table 3. A fraction having a boiling range of 140 to 280° C. obtained from the hydrotreated oil was isomerized using the catalyst B shown in Table 1 under the condition b shown in Table 3. The isomerizing oil after isomerization was cut by distillation into a fraction having a boiling range of 140 to 280° C. to obtain a base 2. The properties of the base 2 are shown in Table 4. An aviation fuel oil composition 2 was prepared by mixing the base 2 with 30 vol % of a hydrocracked kerosene having the properties shown in Table 2 obtained from a heavy oil hydrocracking apparatus.
example 3
[0089]An aviation fuel oil composition 3 was prepared by mixing the aviation fuel oil composition 2 described in Example 2 with 30 vol % of a petroleum-based aviation fuel oil base having the properties shown in Table 2 obtained by refining a crude oil.
