  • Patent number: 10138181
    Abstract: The present invention relates to a method for chlorination and dehydrogenation of ethane, comprising: mixing and reacting a low-melting-point metal chloride with C2H6, such that the low-melting-point metal chloride is reduced to a liquid-state low-melting-point metal, and the C2H6 is chlorinated and dehydrogenized to give a mixed gas containing HCl, C2H6, C2H4, C2H2 and C2H3Cl. In the method, the low-melting-point metal chloride is used as a raw material for chlorination and dehydrogenation, and the low-melting-point metal produced after the reaction is used as an intermediate medium. The method has the characteristics of simple process, low cost and high yield. Moreover, some acetylene and vinyl chloride can be produced as by-products at the same time when the ethylene is produced, by controlling the ratio of ethane to the chloride as desired in production.

  • Patent number: 9056305
    Abstract: 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.
