| Outline of Final Research Achievements |
A new process for renewable diesel production from plant oils was studied, which involves hydrothermal hydrogenation and subsequent decarboxylation. As a result, the optimum condition of hydrothermal hydrogenation was found to be 270℃/5MPa (H2 pressure) in subcritical water with Pd/C catalyst for 1 hour. In this condition, triglycerides, main components of plant oils, were hydrolyzed and hydrogenated simultaneously into saturated fatty acids. Subsequently, saturated fatty acids were converted into hydrocarbons by decarboxylation reaction at 300℃/1MPa (H2 pressure) with Pd/C for 2 hours. Consequently, it was found that the composition of obtained hydrocarbons corresponded to the fatty acid composition of the plant oil used. The fact indicates that the composition of hydrocarbons can be changed to some extent by using various plant oils having different fatty acid composition.
