The recent progress in pitch derived carbon fibers applications. A Review

Research progress in the preparation of mesophase pitch from fluid catalytic cracking slurry

“…Despite quite a few satisfactory results achieved by FCC slurry in the study of preparing mesophase pitch, there are still much space to be improved. Some suggestions, therefore, are presented as below, [139][140][141] (1) The research on the technology and reaction mechanism of co-carbonization, the pilot research on co-carbonization, and systematic research for large-scale industrial application can be carried out.…”

Economic and environmental assessment of asphaltene-derived carbon fiber production

“…Compared to other routes, the A-CF lacks the energy intensive pre-processing step of the precursor itself (such as polymerization for P-CF, hydro-liquefaction for Pi-CF, kraft or steam explosion for L-CF etc.). 11,38,52 The low carbon scenario of A-CF (with hydropower, marked as a black triangle) further highlights the compelling nature in terms of potential climate benefits. However, for the three incumbent routes/feedstocks, the range of energy deviation is extremely high (Table S9 †), which is widely observed in literature reports due to the lack of data transparency.…”

“…6,7 For instance, P-CFs have a tensile strength of ∼3.5-6.8 GPa with a modulus of ∼170-650 GPa, whereas carbon fibers produced from a lignin/isotropic pitch precursor have a tensile strength and a modulus of ∼1 GPa and <80 GPa, respectively. [8][9][10][11] Nevertheless, P-CFs are not affordable for a vast range of midto low-end applications, such as automotive and civil engineering applications, the electricity grid etc. because of its exorbitant production costs that reach ∼$25 per kg.…”

Carbon/NiO Compositional Fibers

“…Recycling coal tar is a great way to produce carbon fibers. However, obtaining carbon fibers from CTP using the electrospinning method is a difficult task [19]. On the other hand, the addition of CTP to PAN solution in the production of carbon fibers is feasible.…”
