Calcium carbide - Wikipedia

Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2,200 °C (3,990 °F). This is an endothermic reaction requiring 110 kilocalories (460 kJ) per mole and high temperatures to drive off the carbon monoxide. This method has not changed since its invention in 1892: CaO + 3 C → CaC2 + CO
