1.Introduction of CBO

Carbon black oil is one high-boiling point fraction of coal tar oil. It is mainly mixed by coal atr pitch and creosote oil. And the proportion is usuallly 40% coal tar pitch and 60% creosote oil . Its sulfur content is always very low. Carbon black oil can be used to produce carbon back in the industry of rubber. In addition, it can be also used in the industry of inks.

2. Application of CBO

Carbon black oil is mainly used to produce carbon black used in the industry of rubber, and also used in the industry of inks.
