Abstract

PURPOSE:To decrease the amount of unreacted carbide, to contribute desulfurization agent to desulfurization reaction effectively, by combining calcium carbide with desulfurization accelerator, constituting of light calcium carbonate as main ingredient, containing very small amount of halogen compounds.
