example 1
[0106]Hydrodeoxygenation treatment was performed by an operation similar to that of Comparative Example 1 except that instead of the hexane-extracted oil in Comparative Example 1, a propane-soluble portion was used that was obtained by repeating propane extraction under the condition (temperature 111° C.) in which the solubility of the hexane-extracted oil in propane under a pressure of 6 MPa was 13.7 g per 100 g of propane, shown in the above-described Table 1, until the recovery rate reached 90% or more. Catalyst deterioration was reduced compared with Comparative Example 1 and Comparative Example 2, and the catalyst deterioration rate indicator was 0.7° C. / day.
example 2
[0107]An operation similar to that of Comparative Example 1 was performed except that instead of the hexane-extracted oil in Comparative Example 1, a propane-soluble portion was used that was obtained by repeating propane extraction under the condition (temperature 112° C.) in which the solubility of the hexane-extracted oil in propane under a pressure of 6 MPa was 8.0 g per 100 g of propane, shown in the above-described Table 1, until the recovery rate reached 90% or more. Catalyst deterioration was further reduced, and the catalyst deterioration rate indicator was 0.5° C. / day.
example 3
[0108]Hydrodeoxygenation treatment was performed by an operation similar to that of Comparative Example 1 except that instead of the hexane-extracted oil in Comparative Example 1, a propane-soluble portion was used that was obtained by repeating propane extraction under the condition (temperature 114° C.) in which the solubility of the hexane-extracted oil in propane under a pressure of 6 MPa was 5.5 g per 100 g of propane, shown in the above-described Table 1, until the recovery rate reached 90% or more. Catalyst deterioration was further reduced, and the catalyst deterioration rate indicator was 0.3° C. / day.
[0109]The results of the Comparative Examples and the Examples described above are collectively shown in Table 4. In addition, impurity concentration in the hexane-extracted oil and the propane-soluble portions obtained by performing propane extraction under the respective conditions, subjected to hydrodeoxygenation treatment, is shown together in Table 4. From the results show...
