Leistenschneider, Desirée, Zuo, Peiyuan, Kim, Yuna, Abedi, Zahra, Ivey, Douglas G., de Klerk, Arno, Zhang, Xuehua, Chen, Weixing
The development of inexpensive carbon fiber precursors is necessary to meet the future demands of carbon fibers. This work shows how asphaltenes, which are obtained as a by-product in bitumen production, can play an important role as such inexpensive carbon fiber precursors. To synthesize carbon...

Oilsands bitumen produced from Alberta, Canada contains 14–20 wt.% n-pentane insoluble asphaltenes. Separation of asphaltenes from the bitumen by solvent deasphalting has the benefit of improving the properties of the deasphalted oil compared to the bitumen, for example, by decreasing its...
