Patent ID: 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.
