A type of calcium coke was developed for use in the oxythermal process of calcium carbide production. The calcium coke was prepared by the copyrolysis of coking coal and calcium carbide slag, which is a solid waste generated from the chloralkali industry. The characteristics of the calcium cokes under different conditions were analyzed experimentally and theoretically. The results show that ...

The main source of sulphur in the BFBOF steelmaking process comes from coke. Even though roughly 40% of the sulphur in coal is removed in the coking process, typical sulphur levels in coke remain around %. Iron ore contains typically % sulphur and is only a minor source of sulphur in the steelmaking process 2, 8.
