Abstract
Calcium carbide is prepared from a powdered lime material. The powdered lime material, possibly together with a reducing agent, is injected with the aid of a carrier gas into a plasma gas generated by a plasma generator. The heated lime material, together with any reducing agent used and the energy-rich plasma gas, is then introduced into a reaction chamber substantially surrounded on all sides by a solid reducing agent in piece form. When the lime material consists of quicklime, this is melted and reduced to liquid carbide and when the lime material consists of powdered limestone, it is burnt directly in the reaction zone to form liquid carbide.
