The main factors affecting the pigment carbon black product quality, first feedstock, production process conditions, granulation and drying.
There FCC decant oil feedstock oil, ethylene tar and coal tar distillate oils with high aromatic content heavy oils. The main use of ethylene tar, anthracene oil and coal tar without fractionation. Of the feedstock requirements are as follows: density is between 1.05 ~ 1.20g / cm³, asphaltenes, water less than 0.5%, ash content less than 0.05%, a sulfur content of less than 0.5% of alkali metal content.
1, combustion gas temperature and flow rate
2, atomization and gasification feedstock
3, reaction temperature and residence time
4, and the amount of additives
5, the production process is stable.
