The decomposition of hydrogen iodide and the separation of the products by the combination of a column packed with an adsorbent with catalytic activity (platinum-supported active carbon, 2.3 wtpercent) and a temperature-swing method (450-900 K) are carried out, and the features and the problems of the method are examined.A one-step conversion of hydrogen iodide, 70percent, is obtained at 450 K, where the equilibrium conversion is 13percent.It is shown that the products of the decomposition of hydrogen iodide containing water are separated from each other.
