N2 - A new process is developed by using compound Mn as intermediate to produce Cl2 from HCl, with the following steps. (1) HCl steam is decomposed by intermediate Mn2O3 to produce Cl2 and MnCl2 at 500 ?C. (2) Produced MnCl2 is oxidized by water steam to produce MnO at 450 ?C. (3) The MnO 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 Cl2 by using Mn2O3 as intermediate in a fixed bed reactor indicate that over 90 of HCl could be converted to Cl2 on stream of 30 h. The production of Cl2 from HCl with Mn compound as an intermediate and atmospheric steam is a feasible and recyclable process.
