| Outline of Final Research Achievements |
Biodiesel fuel (Fatty acid methyl esters: FAME) have lower volatility than petro-diesel fuel due to the larger molecular size of FAME. Recent studies report that the distillation temperature of biodiesel fuel can be lowered by the cross-metathesis reaction with short-chain olefin using ruthenium catalyst. In this study, the effect of cross-metathesis reaction conditions on the
distillation characteristics of reformulated biodiesel fuel is investigated to reveal the reaction conditions for fitting the distillation curve of biodiesel fuels to that of petro-diesel fuel. Furthermore, the reactivity of typical biodiesel fuels such as RME (rapeseed oil), SME
(soybean oil), and WME (waste cooking oil) for crossmetathesis reaction were examined to reveal the reaction conditions appropriate for their fatty-acid compositions.

| Academic Significance and Societal Importance of the Research Achievements |
FAMEはバイオマス由来のため，軽油に代替することで二酸化炭素による地球温暖化防止に繋がる．また，我が国では，FAMEの原料油脂は多様な油脂が混在した廃食油を用いているため，海外の菜種油，大豆油，パーム油のような食糧油と競合しない．さらに，メタセシス反応によって廃食油由来FAMEの組成を低分子化し組成を制御することは，FAMEによるエンジン潤滑油の希釈や低揮発性の課題を解決できるため，FAMEの普及に大きく貢献するばかりでなく，工業的な意義として，既存のFAME製造施設のポスト処理を可能とする新規な提案につながる．
