Abstract[English]
The present technology provides fibers containing high levels of asphaltene but low levels of sulfur and total metals, starting from highly asphaltenic feeds with significant levels of sulfur and total metals. Thus, the present technology provides fibers comprising at least 30 wt% asphaltenes, less than 1 wt% sulfur and less than 0.1% of total metals based on the weight of the fiber. Further, methods of making such asphaltenic fibers are provided, as well as methods of preparing carbon fibers therefrom.[French]
La présente technologie concerne des fibres contenant des niveaux élevés d'asphaltène mais de faibles niveaux de soufre et de métaux totaux, à partir de charges hautement asphalténiques ayant des niveaux importants de soufre et de métaux totaux. Ainsi, la présente technologie fournit des fibres comprenant au moins 30 % en poids d'asphaltènes, moins de 1 % en poids de soufre et moins de 0,1 % de métaux totaux sur la base du poids de la fibre. En outre, l'invention concerne des procédés de fabrication de telles fibres asphalténiques, ainsi que des procédés de préparation de fibres de carbone à partir desdites fibres asphalténiques.
