Abstract
A process is provided for eliminating COS and CS.sub.2 compounds contained in an industrial gas. The gas containing an appropriate quantity of water vapor is contacted with a titanium oxide catalyst arranged in a high temperature reaction zone. The reaction is carried out while maintaining at specific values the ratio R between the number of water vapor moles and the number of moles of the compound(s) COS and CS.sub.2 in the supplied gas in contact with the catalyst, as well as the temperature at the outlet from the reaction zone. The process is applicable to the treatment of industrial gases usable in organic synthesis and containing COS and CS.sub.2 as impurities susceptible of perturbating synthesis reactions.
