摘要: 在两段循环流化床反应器中进行氯化氢催化氧化制氯气的实验. 研究表明,HCl转化率比普通流化床有大幅度提高. 当主要组分为CuCl2的负载型催化剂中的Cu含量为5%时,能够保证反应器的连续顺利运转,而且具有较高的催化活性. 氧氯化段的适宜反应温度为390~400℃,氯化段适宜的反应温度为200~240℃. 在较低的HCl进料空速或较高的O2与HCl进料体积比条件下,HCl转化率较高.

Abstract: For conversion of HCl to Cl2 in a two-zone circulating fluidized bed reactor, a supported CuCl2 catalyst that contains 5% of copper can make the process have a long time smooth run with high activity. In this process, the optimal operation temperatures of oxychlorination zone and chlorination zone are 390~400℃ and 200~240℃, respectively. With the decrease of the volume ratio of HCl to O2 or the WHSV of HCl, the conversion rate of HCl will increase.
