Embodiment
[0100] Hereinafter, the present invention will be described more specifically based on examples, but the present invention is not limited at all by the following examples.
[0101] (to cultivate)
[0102] The culture of euglena was carried out according to the method recorded in the published book "Physiology and Biochemistry of Euglena" (ユグレナ Physiology and Biochemistry), the appendix of the Society Publishing Center (1989) (Society Publishing Center 1 (1989) appendix). Using E.Gracilis Z strain, the utilization area is 1.2m 2 The pool of the Cramer-Myers medium was cultivated outdoors using sunlight for 7 days. Then, anaerobic treatment was performed for a whole day according to the description on page 114 of the same book, and dried at 150° C. to obtain a dry powder of euglena. By repeating the same operation, 1700 g of dried euglena powder that had been anaerobically treated was recovered.
[0103] (solvent extraction)
[0104] Extraction was performed using hexane, wh...
Embodiment 1
[0127] Instead of the hexane-extracted oil of Comparative Example 1, the conditions in which the solubility of the hexane-extracted oil in propane at a pressure of 6 MPa as shown in the aforementioned Table 1 reaches 13.7 g per 100 g of propane (temperature 111° C.) Hydrodeoxygenation treatment was carried out by the same operation as in Comparative Example 1 except that the propane-soluble fraction obtained by repeatedly performing propane extraction until the recovery rate became 90% or more. Compared with Comparative Example 1 and Comparative Example 2, catalyst degradation was alleviated, and the catalyst degradation rate index was 0.7° C. / day.
Embodiment 2
[0129] Instead of the hexane-extracted oil of Comparative Example 1, the conditions in which the solubility of the hexane-extracted oil in propane at a pressure of 6 MPa reached 8.0 g per 100 g of propane (temperature 112° C.) shown in the aforementioned Table 1 were used The same operation as in Comparative Example 1 was performed except that the propane extraction was repeated until the recovery rate became 90% or more of the propane-soluble component obtained. Catalyst degradation was further alleviated, and the catalyst degradation rate index was 0.5°C / day.
