工艺条件对氯化氢催化氧化反应的影响

采用类似Deacon过程的氯化氢催化氧化法制备氯气，选用自制的氯化铜为活性组分的铜基催化剂，通过正交实验考察反应温度、氯化氢与氧气体积比和空速对氯气产率的影响。结果表明，反应温度升高，氯化氢转化率增大；原料氯化氢与氧气体积比减小以及氧气投料量增加，氯化氢转化率明显升高；空速为（0.11~0.15） h^-1时，氯化氢转化率变化不大，空速为0.20 h^-1时，氯化氢转化率明显降低。在反应温度420 ℃、氯化氢与氧气体积比2∶1和空速0.15 h^-1条件下，氯化氢转化率最高，达到76.98%～80.58%。

Influence of process conditions on catalytic oxidation of hydrogen chloride

Using home-made copper-based catalyst with copper dicholoride as the active component, chlo- rine was prepared by hydrogen chloride catalytic-oxidation technology which was similar to Deacon process. The influence of reaction temperature, volume ratio of hydrogen chloride to oxygen and space velocity on chlorine yield was investigated by orthogonal experiments. The results showed that with the enhancement of the reaction temperature, hydrogen chloride conversion increased ; with the decrease of the volume ratio of hydrogen chloride to oxygen and increase of oxygen dosage, hydrogen chloride conversion obviously enhanced. Under space velocity （0.11 -0.15 ） h-1 and more than 0.20 h-1, hydrogen chloride conversion had little change and remarkably reduced, respectively. Under the condition of reaction temper- ature 420 ℃ ,volume ratio of hydrogen chloride to oxygen 2：1 and space velocity 0.15 h-1 ,the maximum conversion of hydrogen chloride reached 76.98% -80.58%.
