摘要
Alumina supported CuCl2 catalyst for oxychlorination of ethane was prepared by impregnation of γ-alumina with an aqueous solution of CuCl2·2H2O and KCl of a various mass fractions. Some samples containing 1%, 3%, 5%, 7%, 9% of Cu and 0%, 2%, 4%, 6%, 8% of K respectively have been investigated. The experiment results indicate that the catalyst containing 5%Cu and 6%K shows the highest yield and selectivity of vinyl chloride. With raising reaction temperature, the catalytic properties of the sample changes dramatically. The conversion of ethane was increased sharply from 320 to 395 ℃ and it was increased slightly from 395 to 440 ℃. At 440 ℃ the conversion of ethane and the yield of vinyl chloride are the highest. Then they are decreased slowly.
