Abstract
The high cost of the present carbon fiberprecursors led researchers to investigate new and cheapersources. Hence, the scientists all over the world have beenmaking their efforts to develop materials suitable to their nativecountry and attempting to find new ways to make carbon fiber.This study aims to investigate the processing of Libyan oilresidues into high quality carbon materials. Samples fromBouri, Es Sider and Amna crude oils were processed by vacuumdistillation and air blowing methods to produce pitchprecursors. Softening point (SP), FT-IR, TGA, and SEM wereperformed to characterize the petroleum pitch, the as spunfibres, the stabilized fibres and the carbon fibres. Vacuumdistillation markedly decreased atomic H/C ratio and increasedaromaticity as well as the softening point. FT-IR analysis of theproduced pitches showed that the relative intensities of thebands associated with aliphatic structure decreased withincreased softening point, while the bands of aromatic structurewere found to be slightly increased. The formation of theoxygenated compounds was the major feature of the air blowingtechnique. The softening point of the blown pitches could beraised to about 1750C, giving a relatively less weight loss (64%).Carbon fibres have been produced successfully from the Bourioil residues. The Bouri Vacuum distilled pitch was successfullymelt-spun into fibres. The resulting fibres were stabilized byoxidation with air. The morphology of the Bouri carbon fiberswas studied by scanning electron microscopy (PDF) Investigation of the Processing of Libyan Crude Oil Residues into Carbon Fibres.
