摘要
对氯化氢催化氧化制氯气的工艺进行了研究,采用γ-Al2O3负载铬活性组分的催化剂,在固定床反应器内反应。铬适宜含量为7%左右,催化剂床层适宜反应温度为420℃,在较低的HCl与O2进料体积比下,HCl的转化率较高。通过多次氧化和分离水的耦合过程,提高了HCl平衡转化率和催化剂处理能力,在较高的HCl与O2进料体积比下,可获得高的HCl转化率。
The conversion of hydrogen chloride to chlorine by catalytic oxidation was researched. The experiment of hydrogen chloride oxidation was carried out in a fixed-bed reactor with catalyst of γ-Al2O3 laden chromium. The optimal content of chromium was about 7 % and the optimal temperature of catalyst bed was 420℃. With the low volume ratio of HCl to O2, the conversion of HCl was higher. More times oxidation in the fixed-bed reactor, coupled by water separation was set up, equilibrium conversation of HCl and catalytic capability were increased. With the high volume ratio of HCl to O2, high conversion of HCl could be obtained.
