3Cl. 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.

The present invention relates to a method for chlorination and dehydrogenation of ethane, involving mixing and reacting a metal chloride with a low boiling point and C2H6, such that the metal chloride with a low boiling point is reduced to a liquid-state metal with a low melting point, and the C2H6 is chlorinated and dehydrogenized to give a mixed gas containing HC1, C2H6, C2H4, C2H2 and C2H3Cl. In the method, the metal chloride with a low boiling point is used as a raw material for chlorination and dehydrogenation, and the metal with a low melting point produced by the reaction is used as an intermediate medium. The method has the characteristics of having a simple process, low costs and a high yield. At the same time, according to production needs, by controlling the ratio of ethane to a chloride, ethylene can be produced, and some acetylene and vinyl chloride can be produced as by-products at the same time.

A catalyst for preparing vinyl chloride, a preparation method therefor and the use thereof. The catalyst for preparing vinyl chloride consists of activated carbon as a support, and a compound supported with barium and a phosphorous compound, with the compounds of barium and phosphor making up 0.2%-20% and 0%-10% by mass percentage respectively, based on the total mass of the catalyst. A water-soluble barium compound and a water-soluble phosphorous compound and an aqueous polymeric monomer are formulated into a solution or emulsion A by adding water; the activated carbon is added into the solution or emulsion A for immersion; the immersed activated carbon is taken out and spin-dried, and then the monomer is polymerised; the polymerised activated carbon is heated and dewatered to decompose and carbonise the polymer; and the carbonised catalyst is activated to obtain the catalyst for preparing vinyl chloride.
