Abstract
For the process of low-temperature reduction of sulphur dioxide, the catalyst based on natural iron-manganese concretions was developed and tested in the target process for obtaining adsorbents in the processes of gas purification from sulphur dioxide. Under the chosen process conditions and the ratio SO2/(CO + H2) = 0.5, the catalyst provides 100 % degree of sulphur dioxide transformation and sulphur yield at a level of 96 %.
