  • 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

  • Calcium Carbide an overview ScienceDirect Topics

    The modern technology used for the production of calcium carbide is based on the reduction of calcium oxide (lime) to CaC 2 by carbon for the overall reaction CaO + 3C = CaC 2 + CO. During this process, impurities such as sulfur and phosphorus, contained in the charge components, are also reduced and dissolved in molten calcium carbide. Calcium and sulfur form a sufficiently strong

  • Reaction kinetics of CaC 2 formation from powder and

    The production of CaC2 from coke/lime powders and compressed powder pellets are low cost and fast processes. A number of studies have reported the reaction kinetics of these reactions but they are still not well understood and the proposed kinetic models are not comparable due to differences in the reaction conditions. Therefore the reaction behavior of CaO/C powders (0.074 mm) and cubes (5 mm

  • Calcium Carbide an overview ScienceDirect Topics

    Acetylene results when calcium carbide, synthesized from limestone and coke at a temperature exceeding 2000 °C, is reacted with water. Direct addition of HCl to acetylene over a mercury chloride/activated carbon catalyst yields VCM. VCM is washed with water and base, and then distilled. Wash water and spent catalyst must be treated to remove and recycle mercury.

  • Properties and production of calcium carbide

    Applications of calcium carbide include manufacture of acetylene gas, and for generation of acetylene in carbide lamps; manufacture of chemicals for fertilizer; and in steel making. Production Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke

  • Development of calcium coke for CaC 2 production using

    A type of calcium coke was developed for use in the oxy-thermal process of calcium carbide production. The calcium coke was prepared by the co-pyrolysis of coking coal and calcium carbide slag, which is a solid waste generated from the chlor-alkali industry. The characteristics of the calcium cokes under different conditions were analyzed experimentally and theoretically.
