Discussion of mixing of different kinds of coal pitches on coking quality
Experimental results and discussion1 Analysis results of thermal reactivity of pitchFrom the experimental results Table 4, it can be seen that the low-quinoline refined pitch treated by the scheme 1, scheme 2, and scheme 3 has relatively good coke quality, while scheme 4 and scheme 5 have unsatisfactory coke quality to view the high quality graphite electrode information.The hi... ...
Effects of mixing of different kinds of coal pitches on coking quality
Effects of mixing of different kinds of coal pitches on coking qualitySeveral different pitches mixed with aromatic oil were carbonized in order to investigate the effects of mixing on the thermal reactivity and the coking quality. The carbonization yield, temperature sudden change and the duration were tested to view graphite products for reference. The microstructures of the ... ...
