| Outline of Final Research Achievements |
To separate a saturated fatty acid from an unsaturated fatty acid contained in low-grade waste cooking oil (WGO), we performed melt crystallization employing an annular-cylindrical-type apparatus. In this study, we examined the following three items: (i) melt crystallization of binary mixture of fatty acids as model WGO, (ii) elucidation of formation mechanism of Taylor vortex in the annular space of a melt crystallization bath, (iii) building of a solute distribution theory using ternary mixture of fatty acids as model WGO.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の実施によって，バイオ燃料精製を目的とした融液晶析における基幹技術と基盤となる理論を確立できた。また，本研究で確立した技術は低品位廃食油の再資源化のために不可欠な精製技術であるため，石油代替資源としての低品位廃食油のエネルギー利用に加えて，炭酸ガス排出量削減などの環境面での波及効果も期待される。
