在世界范围内，存在着开发有效工艺的强烈动机，该工艺允许从HCl废副产品中回收Cl 2，以避免处置这种有毒和腐蚀性材料的需要。我们将描述这样一个过程，已开发的作者的小组，这是目前正在测试中试工厂规模。该方法使用浸渍在高表面积载体上的盐混合物，在两个串联的流化床反应器中交替氯化和氧化。工艺开发包括在宽的温度（25-400°C）和压力（10 - 5 Torr，1 atm）范围内对HCl氧化反应机理的基础研究。我们将对这些研究的结果进行概述。在此基础上，进行了初步的经济评价，并设计建造了中试装置
There exists, worldwide, a strong incentive for the development of efficient processes that permit the recovery of Cl 2 from HCl waste byproducts, to avoid the need for disposal of this toxic and corrosive material. We will describe such a process that has been developed by the author's group and which is currently being tested at the pilot plant scale. The process uses a salt mixture impregnated on a high surface area support alternately chlorinated and oxidized in two fluidized-bed reactors in series. The process development included basic studies of the mechanism of the HCl oxidation reaction over a broad range of temperatures (25-400°C) and pressures (10 -5 Torr, 1 atm). We will present an overview of the results of these studies. On the basis of these investigations, a preliminary economic evaluation was completed and a pilot-plant-scale unit was designed and constructed
