Synthesis of Meso Carbon Micro Beads from Mesophase Pitch by Suspension Method

Abstract

The purpose of this research was to produce Meso Carbon Micro Beads (MCMB) using mesophase pitch as a raw material by suspension method. The effect of pyridine solvent and also carbonization processes in the production of MCMBs were investigated. Finally, the structural and chemical properties of MCMBs were evaluated. The results showed that extraction with pyridine solvent and the carbonization process had a great effect on the morphology and removal of impurities in mesophase pitch and production efficiency. According to the obtained results, the presence of x-ray patterns located at 2θ equal to 26 and 43 degrees confirmed the formation of a graphite hexagonal network. Also, the existence of bands bands and G bands confirmed the existence of regular hexagonal bonds (G) and incomplete bonds (D) in carbon mesophase spheres. At the end of the process, all mesophase pitch particles were converted into carbon mesophase spheres with a particle size distribution of 80 nm to 12 µm.
