  • 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:

  • Calcium Carbide ALMAMET International Group

    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.

    in the furnace charge remain in the calcium carbide product, the lime should contain no more than 0.5 percent each of magnesium oxide, aluminum oxide, and iron oxide, and 0.004 percent phosphorus. Also, the coke charge should be low in ash and sulfur. Analyses indicate that 0.2 to 1.0 percent ash and 5 to 6 percent sulfur are typical in petroleum coke. About 991 kilograms (kg) (2,185 pounds [lb])

    Moisture is removed from coke in a coke dryer, while limestone is converted to lime in a lime kiln. Fines from coke drying and lime operations are removed and may be recycled. The two charge materials are then conveyed to an electric arc furnace, the primary piece of equipment used to produce calcium carbide. There are three basic types of electric arc furnaces: the open furnace, in which the CO burns to carbon dioxide (CO 2 ) when it contacts the air above the charge; the closed furnace,

    The mixture used is coke and lime; Temperature range is set at approximately 2,200 °C; The entire process is carried out in an electric arc furnace; This compound is widely used in the manufacture of acetylene, calcium hydroxide and calcium cyanamide. Application and Uses of Calcium Carbide (CaC2) Calcium Carbide mainly used to produce acetylene gas. Acetylene produced by the reaction of calcium carbide
