- Aqua mesophase pitch (AMP) was prepared through oxidation of coal tar pitch with mixtures of concentrated sulfuric acid and nitric acid.
- Mesophase pitch was melt spun into hollow,ribbon shaped and Y shaped fibers.
- A better separation process is needed to improve the reproducibility and quality of the mesophase pitch precursor.
- Pitch cokes are prepared by carbonization of mesophase pitch and normal pitch at different pressures.
- Carbon foams were prepared from coal tar pitch, petroleum mesophase pitch, and AR pitch.
- Spinnable mesophase pitch was prepared from catalytic cracking residue of petroleum and uniform mesophase pitch carbon fibre (MPPCF) was obtained.
