【摘要】:A new process is developed by using compound Mn as intermediate to produce Cl2from HCl,with the following steps.(1)HCl steam is decomposed by intermediate Mn2O3to produce Cl2and Mn Cl2at 500°C.(2)Produced Mn Cl2is oxidized by water steam to produce Mn O at 450°C.(3)The Mn O compound is oxidized by air to yield Mn2O3.The X-ray diffraction(XRD)crystallite characterization results indicate the high conversion in each step under the optimum experimental conditions.Long term experiments for continuous conversion of HCl to Cl2by using Mn2O3as intermediate in a fixed bed reactor indicate that over 90%of HCl could be converted to Cl2on stream of 30 h.The production of Cl2from HCl with Mn compound as an intermediate and atmospheric steam is a feasible and recyclable process. 【作者单位】: National
