氯化氢催化氧化制氯气工艺

Conversion of Hydrogen Chloride to Chlorine by Catalytic Oxidation

对于氯化氢催化氧化制氯气过程,Cu含量约为12％、主要组份为CuO的负载型催化剂活性高,连续使用200h活性保持不变。将工艺的流程分为氧氯化段和氯化段,既无需对反应过程供热,又能使HCl完全转化成氯气.氧氯化过程的适宜反应条件为:温度360～400℃,原料气的进料比HCl:O_2=2:1,进料总质量空速0.3～0.4kg/(kg催化剂·h)(似下均简称h^(-1));氯化段温度为200℃左右。

For the conversion of hydrogen chloride to chlorine by catalytic oxidation, the suitable catalyst is supported CuO in which there is 12% of copper. It has high activity and its catalytic activity is kept unchanged after running for 200 h. When the process is divided into two stages, oxidative chlorination and chlorination, it is unnecessary to supply heat to the reaction and the conversion of HCI can achieve 100%. The optimal conditions for the stage of oxidative chlorination are: temperature 360-400℃, molar ratio of HCI to O2 2, weight hourly space velocity of the reactants 0.3-0.4 h-1; for the stage of chlorination, the temperature should be about 200℃.
