According to the source, the current carbon black raw material oil can be divided into three categories: one is clarified oil (FCC), which is produced during the production of gasoline by fluid catalytic cracking of gas oil; the other is ethylene tar , which is produced during the steam cracking of naphtha and gas oil to produce ethylene; the third is coal tar fraction, creosote oil and anthracene oil, which are produced during coal coking or gasification.
