CBFS - raw material for manufacture of carbon black
Different fractions of oils are produced during coal tar distillation ranging between 180 and 350 centigrades. The heavier part of the oil is the basic raw material for manufacturing of carbon black.

Parameter "BMCI" measures the degree yield of Carbon Black. The higher the number, the better the yield of Carbon Black. Sulphur content in CBFS reduces the effect of BMCI value.
