Production Methods Of Calcium Carbide Powder

Jan 31, 2011 In recent years, rising oil price promoted industrial development of calcium carbide, and calcium carbide production in China increased from 4.25 million tons in 2002 to 11.77 million tons in 2006. Typically, the calcium carbide production is based on the following reaction formula, i.e. CaO+3C→CaC 2 +CO, which is an endothermic reaction

    Calcium carbide has the nominal formula of CaC 2 and the molecular weight of 64.0992 g/mol. The pure material is colorless, but most samples have a color ranging from black to grayish-white, depending on the grade. Its density is 2.22 g/cc and it melts at 2160 C with a boiling point (under an inert atmosphere) of 2300 C, where it decomposes.Its main use industrially is in the production of

    Development of calcium coke for CaC2 production using

    Sep 21, 2020 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
