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

Calcium carbide. In the 1970s, calcium carbide was introduced as a reagent for hot metal desulphurization. Calcium carbide is made from coke and lime in an electric arc furnace. The coarse fraction is used as base material for acetylene gas generation while the finer fraction is used for preparation of desulphurization reagent.

Abstract. The technical feasibility of making calcium carbide from lime and coke using solar heat was documented in a series of experimental runs conducted at the Odeillo (France) laboratory of the Centre National de la Recherche Scientifique (CNRS), wherein 30 to 40% of the lime-coke mixture was converted to carbide by rapid heating of the reactant mixture in an open, water-cooled crucible.

Carbon dioxide is produced because industrially coke will be present in excess and because at such high temperatures, carbon dioxide is a favourable product compared to pure oxygen. It''s simply because the coke will want to react with the lime and produce carbon dioxide just as much as it wants to make calcium carbide.
