  2. Contents BGBU The Structure for Novel Crystallite Carbon Some Questions

  3. Building from Granular Basic Units (BGBU)

  4. The precursor of the novel crystallite carbon Thermal polycondensation Stacking Pitch molecules BBU of mesophase pitch Mesophase molecule

  5. Yellow dot —the light components in the matrix Basic units Growing trend Three-dimensional structure Novel Crystallite Carbon ? activation carbonization

  6. Stabilization of the mesophase pitch Coal-tar pitch Coal-tar pitch oxygen atom will be brought in Oxidation in the air Delayed coking The product contains many macropores Precursor Precursor

  7. Experiments Coal-tar pitch Temperature and time Controlling Thermal condensation Mesophase pitch Fig.1 Reaction equipment. 1、3. Thermocouples 2. Pressure gauge 4、6. Valve 5. Heating furnace 7. Reaction vessesl 8. Stirring paddle Fig.2 the flowchat of the experiments

  8. Results CTP: coal-tar pitch CTP-360-6: heat treatment at 360℃ for 6 hours CTP-410-0.5: heat treatment at 410℃ for 30min SP: softening point TI: toluene insolubles QI: quinoline insolubles
