Calcium Carbide and Acetylene manufacturing process

Production Process. Steps of production, reactions and physical conditions are discussed in this section. Calcium carbonate decomposition | CaCO 3 = CaO + CO 2. Calcium carbonate is heated into higher temperature and take calcium oxide (CaO). CaCO 3 decomposes into CaO and CO 2 above 825 0 C. Calcium oxide and coke reaction | CaO + C = CaC 2 + CO

Calcium carbonate - Essential Chemical Industry

Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.
