摘要： 提出了由流化床与多段冷激式绝热固定床串联的新型HCl氧化制氯反应工艺. 通过物料、能量、动量衡算建立了绝热反应器一维数学模型，对绝热固定床反应器段间冷激气种类、流率、流化床反应器进口处HCl与O2摩尔配比及催化剂用量等工艺参数进行了优化计算. 结果表明，液态氧为较适宜的冷激气，流化床反应器入口处最佳HCl与O2摩尔配比为1:0.7，流化床和绝热床中最佳催化剂用量分别为4.3与8.6 t，在该条件下，HCl转化率可达85%.

Abstract: A novel HCl oxidation technology combining fluidized bed reactor (FBR) with multi-stage adiabatic fixed bed reactor (MSAFBR) in series was proposed. The operational parameters of HCl oxidation process, such as variety and flow rate of quench gas between MSAFBR, molar ratio of HCl to O2 in feed gas and catalyst dosage, were optimized based on the mathematic one-dimensional model established on the mass, energy and momentum balances. The results showed that liquid oxygen was more suitable in this technology. With liquid oxygen as the quenching
