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

Discovery of Calcium Carbide Process NC DNCR

May 02, 2013 On May 2, 1892, in Spray (now Eden), Canadian chemist Thomas L. Willson accidentally produced calcium carbide and acetylene with an electric-arc furnace. In August, Willson applied for a patent for the new process. By 1897, acetylene was competing with electricity in providing lighting, especially in rural areas and those places where gasoline was unavailable.

Calcium Carbide an overview ScienceDirect Topics

The equipment used for the smelting of calcium carbide is similar to that employed in electric furnaces used for other forms of ferroalloys processing, where carbon is used as a reductant. Calcium carbide is also an intermediate product in the smelting of calcium–silicon alloy. Technical grade calcium carbide is crystallized from the melt and contains ~80% CaC 2 and 10% to 15% CaO (Fig. 19.4).
