在碱性水溶液中的德瓦达合金上,氟里昂12和氯仿由于发生了氢分解,而转化成甲烷、乙烷、丙烷等生成物,氟里昂12的转化率为3.5％,甲烷和乙烷的生成活化能分别是5.4kJ/mol和4.23kJ/mol,氯仿的转化率为8.1％,甲烷生成的选择率在80％以上,氯仿的氢分解反应是基于兰格缪尔(Langmuir)吸附模型,通过求解而确定出了反应的吸附平衡常数k_o和速度常数k_r分别为2.72 1.mol~(-1)和8.55x10~(-6)umol.min~(-1)。 On the Dewar alloy in alkaline aqueous solution, Freon 12 and chloroform are converted to products such as methane, ethane and propane due to the hydrogen decomposition, the conversion of Freon 12 is 3.5%, the conversion of methane and ethane The activation energy of formation is 5.4kJ / mol and 4.23kJ / mol respectively, the conversion of chloroform is 8.1% and the selectivity of methane generation is above 80%. The hydrogen decomposition reaction of chloroform is based on the Langmuir adsorption model The equilibrium constant k_o and the rate constant k_r of the reaction were determined to be 2.72 1.mol -1 and 8.55x10 -6 mol·L -1, respectively.
