Outline of Final Research Achievements

Heavy oils and residues have a very complex organic molecular structure and are difficult to apply. Therefore, the current issue is that a large amount of CO2 is emitted. In this research, we challenged the production of high-performance carbon fiber with strength suitable for automobile bodies using heavy oil and residue. Specifically, heavy oils and residues were converted into "a molecular group in which condensed polycyclic aromatic compounds of 1 to 5 rings are mixed" (carbon fiber precursor), and then carbon fibers were obtained. In this research, we contributed to the creation of a new concept of carbon neutral by converting heavy oils and residues into highly functional carbon materials.

炭素循環社会

Academic Significance and Societal Importance of the Research Achievements

申請者は、『炭素材料で創る炭素循環社会の概念・技術の提案』をしております。過去300年に渡る化石資源文明は人類に繁栄を齎した一方で莫大な二酸化炭素（CO2）消費による環境負荷を顕在化させました。エネルギー源としての化石資源消費時代は終焉を迎えつつあり、新たな『炭素循環社会の創出』が喫緊の課題となっております。これまでの研究では、重質油を原料として炭素材料を製造することで、炭素材としての利用は勿論のこと、材料という形で社会に炭素を貯留する炭素循環に司る研究を行っています。化石資源や残渣を燃料として燃焼させず、炭素材料へ変換すれば、実質的なCO2の搬出は抑えられ炭素循環型社会へ貢献できます。
