摘要： The present invention is concerned with a method of production of acetylene or ethylene. The method has the steps of providing supplies of hydrogen, water, carbon monoxide, carbon dioxide, and methane, respectively, providing a catalyst system having firstly a catalyst selected from group VIII transition metal oxides, and secondly a catalyst support, treating the methane supply with the catalyst system for producing a first reactant, providing a second reactant, and reacting the first reactant with the second reactant for producing an intermediate, wherein the intermediate is calcium carbide (CaC2).

摘要： The present invention relates to a loop-route production method and system for polyvinyl chloride, and belongs to the intersecting fields of coal chemicals, polymer materials and chemical machinery. Limestone and carbon materials such as coal are reacted in an oxygen-enriched high temperature furnace to obtain calcium carbide and carbon monoxide, and then acetylene and carbon monoxide are respectively produced from calcium carbide and dichloroethane (obtaining ethylene, etc., through methanol or ethanol); both of the end products are combined to form a closed-loop; acetylene and dichloroethane are reacted to produce a vinyl chloride monomer, which is polymerized to obtain polyvinyl chloride. The system of the present invention mainly includes a device for pulverizing and mixing solid raw materials, a device for conveying solid materials, an oxygen-enriched calcium carbide furnace, an oxygen-enriched air-blowing device, a tube-shell thermostatic reactor, a fixed bed tubular reactor, a fluidized bed reactor, an acetylene generator having a heat exchanger, a fixed bed reactor and a polymerization reactor. The present invention has the advantages of not only removing the dependence on oil resources during the production of polyvinyl chlorides, but also totally eliminating the mercury pollution.

摘要： An apparatus for the manufacture of acetylene and hydrated lime from the reaction of calcium carbide and an excess of water is disclosed. A primary reactor for the initial reaction of the calcium carbide and water is disposed concentrically within a secondary reactor. Hydrated lime and unreacted calcium carbide flow directly from the primary reactor to the secondary reactor, where the carbide lime settles from the water and is removed.

摘要： A two-stage process for producing acetylene and calcium chloride from calcium carbide and water has two successive reaction steps. In step Number 1, calcium carbide is charged into an entrained flow-type reactor vessel containing water. The reaction which follows proceeds to about 60-90% completion. The entrained reaction products and the unreacted feed material are carried over to a secondary reactor to complete the reaction, and the acetylene gas is drawn off. Calcium hydroxide product is removed from the reactor and reacted with hydrogen chloride to form calcium chloride. Heat generated by the exothermic reactions of water with calcium carbide and HCl with calcium hydroxide is used to dry the calcium chloride product and improve its value. In the presence of excess water, the calcium carbide-water reaction is effectively a first order, irreversible reaction.
