| Abstract: | Mesophase pitches were prepared in different technology processes using 3 kinds of coal bitumens.Polarizing microstructure of the mesophase pitches was observed and analyzed.According to the analysis above,proper technology process of preparing mesophase pitches was achieved.So,for example,for the case of raw material bitumen from Beijing Coking Plant,the good conditions of preparing mesophase pitches would be: final temperature 360℃~400℃,moderate(not too high) pressure,and constant temperature time 6 h~10 h. |
