摘要

Abstract

A new process is developed by using compound Mn as intermediate to produce Cl

from HCl

with the following steps. (1) HCl steam is decomposed by intermediate Mn

to produce Cl

and MnCl

at 500℃. (2) Produced MnCl

is oxidized by water steam to produce MnO at 450℃. (3) The MnO compound is oxidized by air to yield Mn

. 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 Cl

by using Mn

as intermediate in a fixed bed reactor indicate that over 90% of HCl could be converted to Cl

on stream of 30 h. The production of Cl

fromHClwithMn compound as an intermediate and atmospheric steam is a feasible and recyclable process.
