【Abstract】 Carbon black is prepared with ethylene tar in argon and nitrogen plasma. The physical and chemical properties of the carbon black are detected, and its microstructure is analysed by High Revolution Electromicroscopy (HREM) and X-ray Diffraction. The analysis results show the carbon black is similar to acetylene carbon black in microstructure, conductivity, hydrochloric absorption number, DBP, etc. The sample of the carbon black in plasma of higher power is nana-graphite powder. The relationship between microstructure of carbon black and its physical and chemical performance, and technological condition is discussed. 1～2kWh/Liter raw material is needed. There is a mass of hydrogen in flue gas.更多还原
