摘要
The present invention discloses a method for the catalytic reduction of sulfur dioxide, for example in flue gas, by carbon monoxide using lanthanum oxysulfide as the active catalyst. The catalyst is prepared from lanthanum oxide by hydration and sulfidization, the latter step being carried out in the gas stream itself. This method of preparation has more general applicability and can also be used as a method for the preparation of lanthanum, yttrium, gadolinium and lutetium oxysulfides generally.
