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

Calcium Carbide ALMAMET International Group

Technical calcium carbide with a CaC 2 content of about 80% is produced in an electric arc furnace. Calcium carbide (CaC 2) is formed from the chemical reaction of burnt lime and coke in an electric arc at 2,000 to 2,200 °C.. Almamet produces powders and mixtures of calcium carbide for secondary metallurgy in the iron and steel industry, tailored to the requirements profile of the customer.

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

US4594236A Method of manufacturing calcium carbide from

Calcium carbide is prepared from a powdered lime material. The powdered lime material, possibly together with a reducing agent, is injected with the aid of a carrier gas into a plasma gas generated by a plasma generator. The heated lime material, together with any reducing agent used and the energy-rich plasma gas, is then introduced into a reaction chamber substantially surrounded on all

Method of manufacturing calcium carbide from powdered lime

Calcium carbide is manufactured in electric arc furnaces, primarily closed furnaces equipped with Soderberg electrodes. Burnt lime, coke and anthracite are used as raw materials. The raw materials must have a certain particle size (ca. 5-40 mm) to give the correct porosity in the bed and correct electrical conditions in the charge.
