“…3. It is well known that the diameter of pitch fibers obtained by the conventional melt-spinning method are in a range of 10-30 μm [31]. Similarly, the diameter of fibers without applied voltage (only melt-spinning) were approximately 10 μm, corresponding with the aforementioned range of diameter.…”

“…1c-e) calculated by the following formula: beam radiation with a catalyst could result in higher softening points in comparison with heat treatment. Berrueco et al [31] reported that the optimum spinning temperature of pitch it had a eutectic property, which means fibers diameter could be uniform with continuous spinnability. Pitch with low molecular weight generally has poor spinnability, and pitch with wide molecular weight distribution results in non-uniform fiber diameter.…”

Spinnable pitch for melt-electrospinning was obtained from pyrolized fuel oil by electron beam (E-beam) radiation treatment. The modified pitch was characterized by measuring its elemental composition, softening point, viscosity, molecular weight, and spinnability. The softening point and viscosity properties of the modified pitch were influenced by reforming types (heat or E-beam radiation treatment) and the use of a catalyst. The softening point and molecular weight were increased in proportion to absorbed doses of E-beam radiation and added AlCl 3 due to the formation of pitch by free radical polymerization. The range of the molecular weight distribution of the modified pitch becomes narrow with better spinning owing to the generated aromatic compounds with similar molecular weight. The diameter of melt-electrospun pitch fibers under applied power of 20 kV decreased 53% (4.7 ± 0.9 μm) compared to that of melt-spun pitch fibers (10.2 ± 2.8 μm). It is found that E-beam treatment for reforming could be a promising method in terms of time-savings and cost-effectiveness, and the melt-electrospinning method is suitable for the preparation of thinner fibers than those obtained with the conventional melt-spinning method.

“…Currently, there are a number of previous researchers to develop the novel low-cost CFs using lignin [1], liquefied wood [2], anthracene oil [3], biomass tar [4] and pyrolysis fuel oil (PFO) [5] and ethylene bottom oil (EO) [6][7] as an inexpensive raw material. Among them, only a few researches have successfully obtained their CFs with satisfactory mechanical properties.…”

Abstract:The proper hydrogenation of Hyper-coal (HPC) using 1, 2, 3, 4-tetrahydroquinoline (THQ) was able to decrease the oxygen content and adjust the molecular structure of HPC for preparing the spinnable pitch with high softening point (SP). The spinnable pitch prepared from the THQsoluble (QS) fraction of HPC as a precursor consisted more naphthenic carbon groups than that prepared from the 1-methylnaphthalene (1-MN) soluble (MNS) fraction of HPC. The HPC-QS derived spinnable pitch showed excellent spinning performance even the SP of 260°C, and the tensile strength of the resultant carbon fiber was increased to 1350 MPa with a diameter around 8 µm under the only carbonization temperature of at 800°C for 5 min.

“…However, the relatively low carbon content in the PAN precursor also results in cost limitations that have to be overcome. Another precursor of carbon fibers, pitch, is obtained by the distillation process of natural resources such as petroleum and coal [11,12]. The typical raw materials for producing pitch are pyrolysis fuel oil (PFO), catalytic slurry oil, and coal tar.…”

Pitch-based carbon fibers from coal tar or petroleum residue under the same processing condition

Spinnable pitches and carbon fibers were successfully prepared from petroleum or coal pyrolysis residues. After pyrolysis fuel oil (PFO), slurry oil, and coal tar were simply filtered to eliminate the solid impurities, the characteristics of the raw materials were evaluated by elemental analysis, 13 C nuclear magnetic resonance spectrometer, matrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MALDI-TOF-MS), and so on. Spinnable pitches were prepared for melt-spinning carbon fiber through a simple distillation under strong nitrogen flow, and further vacuum distillation to obtain a high softening point. Carbon fibers were produced from the above pitches by single-hole melt spinning and additional heat treatment, for oxidization and carbonization. Even though spinnable pitches and carbon fibers were processed under the same conditions, the melt-spinning and properties of the carbon fiber were different depending on the raw materials. A fine carbon fiber could not be prepared from slurry oil, and the different diameter carbon fibers were produced from the PFO and coal tar pitch. These results seem to be closely correlated with the initial characteristics of the raw materials, under this simple processing condition.
