West Virginia Coal Association | The Conversion of Coal to Acetylene | Research & Development; and concerning, in part: "United States Patent Application 0110123428 - Method and System for Producing Calcium Carbide; 2011; Inventors: Zhenyu Liu, et. al., China; Abstract: A method and a system for producing calcium carbide, the method including mixing powdery carbon-containing raw material with powdery calcium-containing raw material, and directly heating the mixture by combusting a part of carbon-containing raw material in an oxygen-containing atmosphere to produce calcium carbide. The carbon-containing raw material can be coal (and) the calcium-containing raw material can be calcium carbonate ... . , The present invention relates to a method and a system for producing acetylene stones (i.e., calcium carbide (CaC)), and more specially, to a method and a system for producing calcium carbide by providing heat directly through partial combustion of a powdery carbon-containing raw material and a powdery calcium-containing raw material in an oxygen-containing atmosphere. Acetylene stone, i.e. calcium carbide, is one of the basic materials in the organic synthetic chemistry industry. A series of organic compounds can be synthesized by using the calcium carbide as raw material, to provide source materials for fields such as industry, agriculture, and medicine, and calcium carbide is honored as the mother of organic synthesis before the middle of last century. Hydrolysis of calcium carbide results in acetylene and calcium hydroxide";
