  • What Are the Industrial Uses of Calcium Carbide?

    Sep 20, 2019· Calcium carbide is a compound produced from a thermally converted combination of coke and lime. It has several industrial applications, the most frequently encountered being the production of acetylene gas. Acetylene is widely used as a less costly alternative to traditional petroleumbased heating fuels in a number of industrial processes.

  • Discovery of Calcium Carbide Process | NC DNCR

    On May 2, 1892, in Spray (now Eden), Canadian chemist Thomas L. Willson accidentally produced calcium carbide and acetylene with an electricarc furnace. In August, Willson applied for a patent for the new process. By 1897, acetylene was competing with electricity in providing lighting, especially in rural areas and those places where gasoline was unavailable.
