(1) 共同研究の内容
炭化水素系バイオオイルを生産する微細藻類(ボトリオコッカス並びにオーランチオキトリウム)が作る油脂を軽質燃料(ガソリン,ジェット,軽油)へ改質する研究開発を実施する。現段階で最も有力な微細藻類のバイオクルードを用いて,既存石油精製装置並びに物流システムを改造することなく適用可能な“Drop-in Fuel”化技術の確立を目指す。本事業終了時点(平成24年度末)の成果目標として,精製度の違いによるバイオクルード品質への影響を明らかにし,さらに,その品質の違いがバイオクルードの燃料(改質)化反応への影響を把握し,コスト競争力を有するバイオクルード改質技術の可能性を見極める。
英文要約R&D of “Drop-in Fuel” Production from Hydrocarbon Biocrude Synthesized Using Microalgae

R&D Background
 Concern about global warming and depletion of fossil fuels requires the development of sustainable alternative energies. Microalgae have been recognized as a good potential source for biofuel production. However, FAME produced from microalgae have problems when used as diesel because of different properties than petroleum.

R&D Themes and Objectives
 The objective of this R&D is development of conversion technology for hydrocarbon biocrude synthesized by microalgae into “Drop-in fuel” having the same quality as that of petroleum. This study also includes simplification of the biocrude purification step and application of the existing oil refinery technologies.

R&D Results in FY2011
 Squalane was used as a model compound of biocrude. The study of squalane conversion was carried out by applying the existing oil refinery technologies.
 The catalytic cracking technology was used in bio-gasoline production. This study revealed that squalane was easily converted into bio-gasoline compared with petroleum feedstock. The hydro-treating technology was used in bio-jet and bio-diesel production. This study indicated that using a catalyst with acid property is necessary for conversion from squalane into jet/diesel fuel.
 For the simplification of the biocrude extraction/purification step, several methods for cell disruption and lipid extraction were investigated. Vacuum explosion as the disruption method and DME as the extraction solvent were chosen and they are now being examined.
