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. The results show that ...

Production of calcium carbide

The lime necessary for the production of carbide is admitted to the furnaces in the form of calcium oxide (CaO) which is made separately either by subjecting limestone (calcium carbonate, CaCO 3) to combustion (decarbonization) or by dehydrating lime hydrate (calcium hydroxide Ca (OH) 2) obtained by carbide gasification.

 · 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.
