Catalytic Reactions of Acetylene: A Feedstock for the Chemical Industry Revisited

“…In the first reaction step, CaC 2 is formed by the reaction of quicklime and coal at around 2000 °C. Although it is possible to combust coal with oxygen in the presence of CaO, the applied procedure is the melting of CaO with coke in an electrothermal shaft furnace . This first reaction step also produces a stoichiometric amount of CO, which can be converted to synthesis gas by the water gas shift reaction.…”

Global Exploration of the Enthalpy Landscape of Calcium Carbide

“…CaC 2 is commonly used for the production of acetylene . There are additional applications such as desulfurization of iron, production of calcium cyanamide, and carbide lamps…”
