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.

Calcium carbide is made by heating calcium carbonate and subsequently reducing CaO with carbon (e.g., petrol coke). On the other hand Ca(OH)2 is produced as a by-product in the acetylene production. This Ca(OH)2 will react with CO2 to form CaCO3.

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.

Introduction: How to Make Calcium Carbide! Building a carbide furnes. for this project you will need. chipped lime. crushed charcoal. a carbon rod. a welder. when makeing carbide you dont want to use powdered lime as it will blow out of the furnes, you need some thing thats denser. your charcoal also should not be too fine or it will be blown

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
