Calcium carbide is industrially produced in an electric arc furnace with a mixture of coke and lime approximately at 2200 C 3990 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.

11.4 Calcium Carbide Manufacturing 11.4.1 General Calcium carbide CaC2 is manufactured by heating a lime and carbon mixture to 2000 to 2100 C 3632 to 3812 F in an electric arc furnace. At those temperatures the lime is reduced by carbon to calcium carbide and carbon monoxide CO according to the following reaction CaO3C→CaC2 CO
