    • Provided is a method for preparing vinyl chloride with acetylene and dichlorethane for large-scale industrial production. Acetylene, dichlorethane vapor and hydrogen chloride gas at a molar ratio of 1:(0.3-1.0):(0-0.20) are mixed; the raw mixed gas is preheated; the preheated raw mixed gas passes through a reactor containing a catalyst and reacts; the resultant mixed gas is cooled to 30-50° C. and pressurized to 0.4-1.0 MPa, and then cooled to ambient temperature, and further frozen to −25-15° C. for liquefaction isolation, and unliquefied gas is recycled and reused; liquefied liquid is sent to a rectifying tower for rectification, and vinyl chloride monomers meeting polymerization requirements are obtained. The present invention has the advantages of eliminating mercury contamination completely, simplifying the reactor structure, recycling hydrogen chloride and acetylene, reducing waterwash process, avoiding mass production of waste acid and improving utilization of chlorine.

    • The present invention discloses a catalyst used in preparing vinyl chloride, its method of preparation, and its applications. Said catalyst used in making vinyl chloride comprises activated carbon as a support, a barium compound and a phosphorus compound supported thereon. The barium compound accounts for 0.2% to 20% of the total mass of the catalyst and the phosphorus compound accounts for 0% to 10% of the total mass of the catalyst based on the mass percentage. A water-soluble barium compound, a water-soluble phosphorus compound, an aqueous polymer monomer, and water are mixed to form a solution or emulsion A. The activated carbon is added into the solution or emulsion A. The activated carbon is removed from water after impregnation, spin-dried, and then the monomers are polymerized. The activated carbon, after polymerization step, is heated to remove water and to decompose and carbonize the polymer. The catalyst after carbonization was activated to obtain a catalyst used in making vinyl chloride.
