11.4 Calcium Carbide Manufacturing - US EPA

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

We have performed several tests for each of the contents ...

Calcium Carbide - Structure, Production, Uses and FAQs - VEDANTU

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. The high ...
