11.4 Calcium Carbide Manufacturing

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: CaO+3C→CaC2 +CO

Properties and production of calcium carbide

Calcium carbide are grey or brown and consist of about 80 ±85% of CaC2(the rest is CaO (calcium oxide), Ca3P2(calcium phosphide), CaS (calcium sulfide), Ca3N2(calcium nitride), SiC (silicon carbide), etc.). In the presence of trace moisture, technical-grade calcium carbide emits an unpleasant odor reminiscent of garlic.

Calcium carbide - Wikipedia

Production. 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 → CaC 2 + CO
