Abstract:
Using solvents extraction separation system of self-designed make superior coal tar pitches for carbon materials. In proper order choose petroleum ether, methanol and carbon disulfide to cut coal tar into several fractions under different condition. The first solvent can take light components out from coal tar. Then drag out those chemical that contain heteroatom such as nitrogen, sulfide applying the second solvent. The last is to dig out higher molecular weight polycyclic aromatic hydrocarbon from coal tar deeply. Heavy fractions are vacuumed to drive out any solvents. The superior chirpy coal tar pitches for carbon materials acquired.
