1, natural calcined petroleum coke carbonizer, which is not calcined at high temperature, or the calcination temperature is low and the time is short. Nitrogen content is generally around 1000PPm, that is, 0.1%, nitrogen content is high, its sulfur content is also high. In the white paper can not draw clear traces.
2, high temperature calcined petroleum coke carbonizer, nitrogen content of about 500PPm, that is, 0.05% or so. Sulfur is much lower than natural calcination. It can leave clear traces on white paper.
3, graphite column particles of carbonizer, graphite powder plus binder, after kneading into cylindrical particles of carbonizer. This kind of carbonizer due to carbon are presented in the shape of graphite, furnace absorption is particularly good, and the above high-temperature calcined petroleum coke is virtually the same. Trained workers think this carbonizer is very good, with low sulfur and low nitrogen content. Generally below 600ppm, including 600ppm, or 0.06%.
4, coal carbonizer, including bituminous coal and anthracite, nitrogen content according to the quality of coal, nitrogen content is different, generally in 2000 ~ 7000PPm, that is, 0.2% ~ 0.7%.
