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

Calcium carbide is the most industrially relevant carbide because of its important role as the basis of the acetylene industry. In locations where there is a shortage of petroleum, calcium carbide is used as the starting material for the production of acetylene, which, in turn, can be used as a building block for a range of organic chemicals, such as vinyl acetate, acetaldehyde and acetic acid.

· Calcium carbide is industrially produced in an electric arc furnace with a mixture of coke and lime, approximately at 2,200 °C (3,990 °F). This is an endothermic reaction that requires a high temperature to drive off the carbon monoxide at 110 kilocalories (460 kJ) per mole. Since its invention in 1892, this method has not changed.
